What is AVE? -AVE (Agentic Vulnerability Enumeration) is an open numbering system for vulnerabilities found in **agentic AI components** β€” the files, servers, prompts, and protocols that define what an AI agent can do and how it behaves. +AVE is an open numbering system for vulnerabilities in agentic AI components: +skill files, MCP servers, system prompts, agent plugins, A2A protocols, and +RAG knowledge bases. -AVE records are the operational intelligence layer for AI agent security. Each record describes: +Each record answers four questions: -- **What** the vulnerability is (attack class, behavioral description) -- **Where** it appears (component type, affected registries) -- **How dangerous** it is (CVSS-AI score, agentic impact dimensions) -- **How to find it** (behavioral fingerprint, detection methodology) -- **How it maps** to established frameworks (OWASP, NIST, MITRE ATLAS) +- **What** is the vulnerability?

(OWASP AIVSS v0.8 score, agentic risk factors) +- **How do you find it?** (behavioral fingerprint, detection rules, IOCs) -AVE is maintained by [Bawbel](https://bawbel.io) and powered by [PiranhaDB](https://bawbel.io) β€” the first global behavioral threat intelligence database for agentic AI components. The specification is open. Any tool can implement it. Any researcher can submit records. +AVE records power [bawbel-scanner](https://github.com/bawbel/bawbel-scanner) +and are indexed in [PiranhaDB](https://api.piranha.bawbel.io), the public +threat intelligence API for agentic AI components. + +The specification is open.

Why not CVE? -CVE (Common Vulnerabilities and Exposures) was designed in 1999 for deterministic software flaws β€” buffer overflows, SQL injection, use-after-free. It works exceptionally well for that problem. AVE is not a replacement for CVE. It covers a fundamentally different attack surface. +CVE was designed in 1999 for deterministic software flaws. It works well for +buffer overflows, SQL injection, and use-after-free. AVE covers a different +attack surface. | Dimension | CVE | AVE | |---|---|---| -| **Vulnerability type** | Deterministic code flaw | Behavioral, probabilistic, natural language | -| **Subject** | Specific software version | Agentic component (any format, any platform) | -| **Reproducibility** | Exact reproduction required | Behavioral pattern matching | -| **Patching model** | Vendor issues patched version | Component removed, replaced, or behavioral policy applied | -| **Mutation tracking** | One CVE per instance | One AVE record covers all behavioral variants | -| **Scoring** | CVSS (network, auth, impact) | CVSS-AI (adds agentic scope, human oversight, tool access) | -| **Disclosure target** | Software vendor | Registry operator, platform maintainer, or community | -| **Processing speed** | Days to months | Near real-time via PiranhaDB | -| **Coverage** | Code vulnerabilities only | Skills, MCP servers, prompts, plugins, A2A protocols, RAG, models | - -**If a SKILL.md file contains a traditional RCE in embedded Python code, that gets a CVE.** The natural language prompt injection instruction in the same SKILL.md that hijacks the agent's goals β€” that gets an AVE.

Scope β€” What AVE Covers +## 3. Governance -AVE covers every type of **agentic component** β€” any artifact that defines an AI agent's capabilities, behavior, or permissions. +AVE v0.2.0 is maintained by [Bawbel](https://bawbel.io). -| Component Type | `component_type` value | Examples | Primary Attack Classes | -|---|---|---|---| -| Skill files | `skill` | SKILL.md, .cursorrules, CLAUDE.md, Codex skills | Prompt injection, goal hijack, shadow permissions, metamorphic payloads | -| MCP servers | `mcp` | Any MCP-compatible server manifest | Tool poisoning, unauthorized execution, SQL injection via MCP, MPMA | -| System prompts | `prompt` | LLM deployment instructions | Jailbreaking, safety bypass, PII leakage, instruction injection | -| Agent plugins | `plugin` | Copilot plugins, AgentForce skills, Bedrock agents | Supply chain poisoning, capability escalation, exfiltration | -| A2A protocols | `a2a` | Google A2A handlers, Anthropic multi-agent configs | Transitive trust exploitation, agent impersonation, lateral movement | -| RAG knowledge bases | `rag` | LlamaIndex, LangChain, Bedrock KB sources | Data poisoning, indirect prompt injection, exfiltration via retrieval | -| Fine-tuned models | `model` | Hugging Face models, Azure AI, Vertex AI | Model poisoning, backdoor triggers, capability manipulation | - -**Out of scope for AVE:** -- Traditional code vulnerabilities in software that powers agents (use CVE) -- Model alignment failures not caused by deliberate adversarial input (use ML safety frameworks) -- Privacy violations not arising from agentic component behavior (use applicable privacy frameworks) +### Current state ---- +Bawbel owns the AVE numbering system, the record schema, and the PiranhaDB +API. The specification is open source (Apache 2.0). Anyone can read it, +implement it, submit records, and propose changes via GitHub pull request. +Bawbel makes final decisions on schema changes and record acceptance today. -## 4. AVE ID Format - -``` -AVE-{YEAR}-{SEQUENCE} -``` +### Guiding principle -**Examples:** -``` -AVE-2026-00001 -AVE-2026-00142 -AVE-2026-01000 -``` +The long-term goal is for AVE to be governed by a neutral body where no +single organization holds a majority. What that body looks like, whether +an existing foundation such as OWASP, the Linux Foundation, or OpenSSF, +or something new, will be decided based on what the community and ecosystem +actually support.

Do NOT create a new record. +Instead, note it as a sub-case in the parent record's description or +indicators_of_compromise. A variant never gets its own ave_id. +Example: "tool poisoning via unicode tag smuggling" is a variant of +tool_description_injection, not a new class. + +**OUT OF SCOPE** β€” a real, often ATLAS-catalogued attack that AVE +deliberately does not cover because it targets the model or training +pipeline, not an agent component. Log it as out of scope with the reason. +This is not a gap β€” it is the boundary of the standard. +Example: ATLAS data poisoning of training data, model extraction, +membership inference β†’ OUT OF SCOPE (AVE covers agent components, not +model training or inference). + +**NEW CLASS** β€” no existing record describes this behavior, it is in scope +(an agent-component behavior), and it is not a thin variant. It operates on +a different surface, exploits a different trust assumption, or chains +differently. This earns a new record. +Example: "parasitic toolchain attack β€” multi-tool collaboration without a +single malicious server" is behaviorally distinct from single-server tool +poisoning β†’ NEW CLASS. + +The bar for NEW CLASS is the deletion test applied to taxonomy: +"If we folded this into an existing record, would we lose a real +detection distinction, or just add a synonym?"

What is AVE? - -AVE is an open numbering system for vulnerabilities in agentic AI components: -skill files, MCP servers, system prompts, agent plugins, A2A protocols, and -RAG knowledge bases. - -Each record answers four questions: - -- **What** is the vulnerability? (attack class, behavioral description) -- **Where** does it appear? (component type, affected registries, platforms) -- **How dangerous** is it? (OWASP AIVSS v0.8 score, agentic risk factors) -- **How do you find it?** (behavioral fingerprint, detection rules, IOCs) - -AVE records power [bawbel-scanner](https://github.com/bawbel/bawbel-scanner) -and are indexed in [PiranhaDB](https://api.piranha.bawbel.io), the public -threat intelligence API for agentic AI components. - -The specification is open. Any tool can implement it. Any researcher can -submit records. - ---- - -## 2. Why not CVE? - -CVE was designed in 1999 for deterministic software flaws. It works well for -buffer overflows, SQL injection, and use-after-free. AVE covers a different -attack surface. - -| Dimension | CVE | AVE | -|---|---|---| -| Vulnerability type | Deterministic code flaw | Behavioral, probabilistic, natural language | -| Subject | Specific software version | Agentic component (any format, any platform) | -| Reproducibility | Exact reproduction required | Behavioral pattern matching | -| Patching | Vendor issues patched version | Component removed or behavioral policy applied | -| Mutation tracking | One CVE per instance | One record covers all behavioral variants | -| Scoring | CVSS | OWASP AIVSS v0.8 | -| Processing speed | Days to months | Near real-time via PiranhaDB | - -AVE and CVE are complementary. A SKILL.md with a traditional RCE in embedded -Python gets a CVE. The prompt injection instruction in the same file that -hijacks the agent's goals gets an AVE. Both are necessary. - ---- - -## 3. Governance - -AVE v0.2.0 is maintained by [Bawbel](https://bawbel.io). - -### Current state - -Bawbel owns the AVE numbering system, the record schema, and the PiranhaDB -API. The specification is open source (Apache 2.0). Anyone can read it, -implement it, submit records, and propose changes via GitHub pull request. -Bawbel makes final decisions on schema changes and record acceptance today. - -### Guiding principle - -The long-term goal is for AVE to be governed by a neutral body where no -single organization holds a majority. What that body looks like, whether -an existing foundation such as OWASP, the Linux Foundation, or OpenSSF, -or something new, will be decided based on what the community and ecosystem -actually support. We are not planning that in advance. - -Bawbel's commitment: when AVE reaches the adoption level where neutral -governance makes sense, we will transfer ownership. We will not use -governance control to extract commercial advantage from the standard. - -### How to participate now - -- Submit AVE records via pull request (see [Section 9](#9-submitting-a-record)) -- Propose schema changes by opening a GitHub issue -- Implement AVE in your own tools (Apache 2.0, no permission needed) -- If your organization is interested in co-governing AVE as it matures, - email bawbel.io@gmail.com subject: `AVE Governance: [organization name]` - - ---- - -## 4.

Problem β†’ standard β†’ why it wins β†’ the prize
+
+ +

The gap AVE fills

+

Conventional vulnerability standards were built for conventional software.

+

CVE identifies a flaw, CVSS scores its severity, and OSV maps it to a specific package and version range. This works because traditional vulnerabilities live in code you can pin to a release.

+

Agent component threats do not. A prompt injection hidden in an MCP tool description, a skill file that fetches its real instructions from a remote URL, a rug pull that changes behavior after install, a toxic flow that chains two individually-benign capabilities into an exfiltration path β€” none of these map to a package and version. The same malicious behavior appears in infinitely many textual forms, and the danger is in what the component does, not which dependency it pulls. That is the gap: the existing standards are blind to it because there is no package to flag and no version range to constrain.

+ +

What AVE is

+

AVE is an open standard that assigns a stable identifier to each distinct behavioral vulnerability class in agentic AI. Each record describes the behavior that makes a component dangerous, scores it with OWASP AIVSS v0.8, and maps it to the frameworks the field already uses. It is behavioral, not signature-based β€” one record catches many textual variants of the same underlying attack. AVE is a standard, not a product: the Bawbel scanner implements it, but it is designed to be implemented by anyone.

+ +

Why it wins

+
+
+ 01 +

Trusted frameworks

+

Every record maps to OWASP MCP Top 10, OWASP Agentic AI Top 10, and MITRE ATLAS, scored with OWASP AIVSS v0.8. AVE does not replace a framework β€” it gives teams a lintable way to enforce one.

+
+
+ 02 +

Scanner interoperability

+

Independent studies find different agent-security scanners barely agree on what they flag. That is a vocabulary problem, not a quality one. AVE is the shared reference that makes cross-tool findings comparable.

+
+
+ 03 +

Open governance

+

A standard owned by one company invites lock-in fear. AVE is Apache 2.0 with an explicit path toward neutral governance as an OWASP project β€” meant to outlive any single implementation.

+
+
+ +
+ The prize +

If the field adopts one vocabulary, findings from any tool interoperate and a security team can finally compare and correlate results across scanners. That is the position AVE is built to occupy β€” the CVE moment for AI agents.

Anatomy of a record

+

An AVE record is a single JSON file at records/AVE-YYYY-NNNNN.json that validates against schema/ave-record.schema.json (currently v1.1). It has two conceptual halves.

+ +
+
+

Definition β€” static

+
    +
  • ave_id β€” immutable identifier, never renumbered
    • +
  • attack_class β€” behavioral category
    • +
  • behavioral_fingerprint β€” what it does
    • +
  • severity Β· aivss β€” AIVSS v0.8 breakdown
    • +
  • owasp_mcp Β· owasp Β· mitre_atlas β€” mappings
    • +
  • remediation Β· iocs Β· references
    • +
+
+
+

Evidence declarations β€” v1.1

+
    +
  • confidence_baseline β€” base confidence
    • +
  • evidence_kind_default β€” default kind
    • +
  • detection_stage β€” earliest detectable
    • +
  • detection_layer β€” where it surfaces
    • +
  • evidence_basis_engines β€” which engines
    • +
  • derivable_into β€” toxic-flow chains
    • +
+
+
+

The static definition describes the vulnerability class itself and never changes per scan. ave_id is immutable β€” once published it is never renumbered or reused; a wrong record is deprecated via status, never deleted. behavioral_fingerprint is the heart of the record: it describes what the component does, not a byte signature. Severity and aivss_score must agree β€” CRITICAL implies a score of 9.0 or higher.

+

The evidence declarations were added in schema v1.1 (issues #69–72). They are all optional, so every pre-v1.1 record still validates. Crucially, they do not carry per-detection values β€” they declare the defaults and baselines a scanner uses to assign per-finding evidence metadata.

+ +

Validation β€” the record/rule/fixture triangle

+

A definition nobody can detect is not useful, and a detection with no false-positive guard is a liability. Every record therefore requires three things beyond the JSON:

+
    +
  • A rule (pattern, yara, or semgrep) that implements detection and references the ave_id.
    • +
  • A positive fixture β€” a file that must trigger the rule.
    • +
  • A negative fixture β€” a benign file that resembles the positive one but must not trigger. This is the false-positive guard, and a rule without one is incomplete.
    • +
+

The tooling in scripts/ enforces that every record has a rule and every rule has both fixtures. pytest runs the rules against the fixtures and fails if a positive fixture stops triggering or a negative fixture starts.

+ +

Consumption β€” the record declares, the scanner assigns

+

This is the most important concept for anyone implementing AVE, and the reason the v1.1 evidence fields exist.

+

An AVE record is static. A scanner Finding is a runtime instance β€” one detection of one file at one moment. Confidence belongs to the Finding, never to the record: the same class detected in a docs/ folder and in a live skill file deserves different confidence. So the record never carries a confidence number. It declares the baseline, and the scanner does the per-detection math.

+ + + + + + + + + + + + +
Record declares β€” staticScanner assigns to Finding β€” runtime
confidence_baseline→confidence (then FP-adjusted)
evidence_kind_default→evidence_kind
detection_stage→evidence_stage (floor)
evidence_basis_engines→evidence_basis
derivable_into→ToxicFlow.derived_from_findings
+ +
+ Core invariant +

In any Finding, confidence and aivss_score are separate fields with separate meaning and are never merged or substituted. AIVSS answers "how bad would this be"; confidence answers "how sure are we." A HIGH-severity low-confidence finding and a HIGH-severity high-confidence finding demand different responses, and the output keeps them distinct.

+
+ +
+ Why baselines live in the standard +

If the scanner hardcoded these baselines, a second implementation would invent its own and the two tools would produce divergent evidence metadata for the same class. Baselines belong in the standard so every implementation agrees. See docs/adr/0003-records-declare-baselines.md.

+
+ +

What stays out of the record

+

These are per-detection runtime values. They live only on the scanner Finding, never in an AVE record: confidence, confidence_band, the actual evidence_stage reached, confidence_reason, derived, line, match, suppressed, and the engine that actually fired.

+ +

Output and distribution

+
    +
  • SARIF. A scanner emits Findings as SARIF with the ave_id in ruleId and referenced under taxonomies, plus aivss_score, confidence, owasp_mcp, and mitre_atlas in the properties bag. Because SARIF is already consumed by the GitHub Security tab and CI, AVE ids travel into those surfaces for free.
    • +
  • PiranhaDB and the public site. The record set is ingested by PiranhaDB via the deploy-time sync_records.py export and served at api.piranha.bawbel.io and the public registry at ave.bawbel.io.
    • +
  • Crosswalks. Published mappings let other scanners' finding types resolve to AVE ids, so findings from different tools become comparable through the AVE layer.

Every record therefore requires three +things beyond the JSON: + +1. A **rule** (`pattern`, `yara`, or `semgrep`) that implements detection and + references the `ave_id`. +2. A **positive fixture** β€” a file that must trigger the rule. +3. A **negative fixture** β€” a benign file that resembles the positive one but + must *not* trigger the rule. This is the false-positive guard, and a rule + without one is incomplete. + +The validation tooling in `scripts/` enforces that every record has a rule +and that every rule has both fixtures. `pytest` runs the rules against the +fixtures and fails if a positive fixture stops triggering or a negative +fixture starts. + +### Consumption β€” the record declares, the scanner assigns + +This is the most important concept for anyone implementing AVE, and the +reason the v1.1 evidence fields exist. + +An AVE **record** is static. A scanner **Finding** is a runtime instance β€” +one detection of one file at one moment. Confidence belongs to the Finding, +never to the record: the same class detected in a `docs/` folder and in a +live skill file deserves different confidence. So the record never carries a +`confidence` number. Instead it declares the baseline, and the scanner does +the per-detection math: + +| Record DECLARES (static) | Scanner ASSIGNS to Finding (runtime) | +|---|---| +| `confidence_baseline` | `confidence` (then FP-adjusted) | +| `evidence_kind_default` | `evidence_kind` | +| `detection_stage` | `evidence_stage` (floor) | +| `evidence_basis_engines` | `evidence_basis` | +| `derivable_into` | `ToxicFlow.derived_from_findings` | + +The invariant that falls out of this: in any Finding, `confidence` and +`aivss_score` are separate fields with separate meaning and are never merged +or substituted. AIVSS answers "how bad would this be"; confidence answers +"how sure are we." A HIGH-severity, low-confidence finding and a HIGH-severity, +high-confidence finding require different responses, and the output keeps +them distinct. + +Putting the baselines in the standard rather than in scanner code is +deliberate. If the scanner hardcoded them, a second implementation would +invent its own and the two tools would produce divergent evidence metadata +for the same class. Baselines belong in the standard so every implementation +agrees. (See `docs/adr/0003-records-declare-baselines.md`.) + +### What stays out of the record + +These are per-detection runtime values. They live only on the scanner +Finding, never in an AVE record: `confidence`, `confidence_band`, the actual +`evidence_stage` reached, `confidence_reason`, `derived`, `line`, `match`, +`suppressed`, and the engine that actually fired. + +### Output and distribution + +- **SARIF.** A scanner emits Findings as SARIF with the `ave_id` in `ruleId` + and referenced under `taxonomies`, plus `aivss_score`, `confidence`, + `owasp_mcp`, and `mitre_atlas` in the properties bag. Because SARIF is + already consumed by the GitHub Security tab and CI systems, AVE ids travel + into those surfaces for free. +- **PiranhaDB and the public site.** The record set is ingested by PiranhaDB + (the deploy-time `sync_records.py` export) and served at + `api.piranha.bawbel.io` and the public registry at `ave.bawbel.io`. +- **Crosswalks.** Published mappings let other scanners' finding types + (SkillSpector's categories, ClawScan's types) resolve to AVE ids, so + findings from different tools become comparable through the AVE layer. + +### Adding a record + +Use the `add-ave-record` skill.

-
- -

The gap AVE fills

-

Conventional vulnerability standards were built for conventional software.

-

CVE identifies a flaw, CVSS scores its severity, and OSV maps it to a specific package and version range. This works because traditional vulnerabilities live in code you can pin to a release.

-

Agent component threats do not. A prompt injection hidden in an MCP tool description, a skill file that fetches its real instructions from a remote URL, a rug pull that changes behavior after install, a toxic flow that chains two individually-benign capabilities into an exfiltration path β€” none of these map to a package and version. The same malicious behavior appears in infinitely many textual forms, and the danger is in what the component does, not which dependency it pulls. That is the gap: the existing standards are blind to it because there is no package to flag and no version range to constrain.

- -

What AVE is

-

AVE is an open standard that assigns a stable identifier to each distinct behavioral vulnerability class in agentic AI. Each record describes the behavior that makes a component dangerous, scores it with OWASP AIVSS v0.8, and maps it to the frameworks the field already uses. It is behavioral, not signature-based β€” one record catches many textual variants of the same underlying attack. AVE is a standard, not a product: the Bawbel scanner implements it, but it is designed to be implemented by anyone.

- -

Why it wins

-
-
- 01 -

Trusted frameworks

-

Every record maps to OWASP MCP Top 10, OWASP Agentic AI Top 10, and MITRE ATLAS, scored with OWASP AIVSS v0.8. AVE does not replace a framework β€” it gives teams a lintable way to enforce one.

-
-
- 02 -

Scanner interoperability

-

Independent studies find different agent-security scanners barely agree on what they flag. That is a vocabulary problem, not a quality one. AVE is the shared reference that makes cross-tool findings comparable.

-
-
- 03 -

Open governance

-

A standard owned by one company invites lock-in fear. AVE is Apache 2.0 with an explicit path toward neutral governance as an OWASP project β€” meant to outlive any single implementation.

-
-
- -
- The prize -

If the field adopts one vocabulary, findings from any tool interoperate and a security team can finally compare and correlate results across scanners. That is the position AVE is built to occupy β€” the CVE moment for AI agents.

Anatomy of a record

-

An AVE record is a single JSON file at records/AVE-YYYY-NNNNN.json that validates against schema/ave-record.schema.json (currently v1.1). It has two conceptual halves.

- -
-
-

Definition β€” static

-
    -
  • ave_id β€” immutable identifier, never renumbered
    • -
  • attack_class β€” behavioral category
    • -
  • behavioral_fingerprint β€” what it does
    • -
  • severity Β· aivss β€” AIVSS v0.8 breakdown
    • -
  • owasp_mcp Β· owasp Β· mitre_atlas β€” mappings
    • -
  • remediation Β· iocs Β· references
    • -
-
-
-

Evidence declarations β€” v1.1

-
    -
  • confidence_baseline β€” base confidence
    • -
  • evidence_kind_default β€” default kind
    • -
  • detection_stage β€” earliest detectable
    • -
  • detection_layer β€” where it surfaces
    • -
  • evidence_basis_engines β€” which engines
    • -
  • derivable_into β€” toxic-flow chains
    • -
-
-
-

The static definition describes the vulnerability class itself and never changes per scan. ave_id is immutable β€” once published it is never renumbered or reused; a wrong record is deprecated via status, never deleted. behavioral_fingerprint is the heart of the record: it describes what the component does, not a byte signature. Severity and aivss_score must agree β€” CRITICAL implies a score of 9.0 or higher.

-

The evidence declarations were added in schema v1.1 (issues #69–72). They are all optional, so every pre-v1.1 record still validates. Crucially, they do not carry per-detection values β€” they declare the defaults and baselines a scanner uses to assign per-finding evidence metadata.

- -

Validation β€” the record/rule/fixture triangle

-

A definition nobody can detect is not useful, and a detection with no false-positive guard is a liability. Every record therefore requires three things beyond the JSON:

-
    -
  • A rule (pattern, yara, or semgrep) that implements detection and references the ave_id.
    • -
  • A positive fixture β€” a file that must trigger the rule.
    • -
  • A negative fixture β€” a benign file that resembles the positive one but must not trigger. This is the false-positive guard, and a rule without one is incomplete.
    • -
-

The tooling in scripts/ enforces that every record has a rule and every rule has both fixtures. pytest runs the rules against the fixtures and fails if a positive fixture stops triggering or a negative fixture starts.

- -

Consumption β€” the record declares, the scanner assigns

-

This is the most important concept for anyone implementing AVE, and the reason the v1.1 evidence fields exist.

-

An AVE record is static. A scanner Finding is a runtime instance β€” one detection of one file at one moment. Confidence belongs to the Finding, never to the record: the same class detected in a docs/ folder and in a live skill file deserves different confidence. So the record never carries a confidence number. It declares the baseline, and the scanner does the per-detection math.

- - - - - - - - - - - - -
Record declares β€” staticScanner assigns to Finding β€” runtime
confidence_baseline→confidence (then FP-adjusted)
evidence_kind_default→evidence_kind
detection_stage→evidence_stage (floor)
evidence_basis_engines→evidence_basis
derivable_into→ToxicFlow.derived_from_findings
- -
- Core invariant -

In any Finding, confidence and aivss_score are separate fields with separate meaning and are never merged or substituted. AIVSS answers "how bad would this be"; confidence answers "how sure are we." A HIGH-severity low-confidence finding and a HIGH-severity high-confidence finding demand different responses, and the output keeps them distinct.

-
- -
- Why baselines live in the standard -

If the scanner hardcoded these baselines, a second implementation would invent its own and the two tools would produce divergent evidence metadata for the same class. Baselines belong in the standard so every implementation agrees. See docs/adr/0003-records-declare-baselines.md.

-
- -

What stays out of the record

-

These are per-detection runtime values. They live only on the scanner Finding, never in an AVE record: confidence, confidence_band, the actual evidence_stage reached, confidence_reason, derived, line, match, suppressed, and the engine that actually fired.

- -

Output and distribution

-
    -
  • SARIF. A scanner emits Findings as SARIF with the ave_id in ruleId and referenced under taxonomies, plus aivss_score, confidence, owasp_mcp, and mitre_atlas in the properties bag. Because SARIF is already consumed by the GitHub Security tab and CI, AVE ids travel into those surfaces for free.
    • -
  • PiranhaDB and the public site. The record set is ingested by PiranhaDB via the deploy-time sync_records.py export and served at api.piranha.bawbel.io and the public registry at ave.bawbel.io.
    • -
  • Crosswalks. Published mappings let other scanners' finding types resolve to AVE ids, so findings from different tools become comparable through the AVE layer.

The schema's `detection_layer` +enum is fixed: `content | server_card | registry_metadata | runtime | transport`. None +of these precisely names "the vulnerable code is the tool's own implementation, found by +SAST/code review of source, not by scanning prompt text." + +Both issues currently propose `content` as "closest existing enum value" with an +explicit flag that this stretches the taxonomy. Three options: + +- **(a) Reuse `content`.** No schema change, ships immediately. Costs a small semantic + overload: `content` now means both "natural-language instruction text" and "the tool's + own source code," which a future reader of `docs/architecture/ave-architecture.md`'s + five-layer table won't expect. Cheapest, and matches how AVE already tolerates + `detection_layer` being a coarse five-bucket classification rather than a precise + scanner-routing key (see `evidence_basis_engines` as the actual routing signal). +- **(b) Add a sixth enum value** (e.g. `implementation`). This is a structural schema + change under CONTRIBUTING.md's "Schema changes" section β€” requires its own issue and a + 30-day comment period before merging, which blocks this entire batch on a slower + track than the records themselves need. +- **(c) Leave `detection_layer` as `content` but make the distinction explicit in + `behavioral_fingerprint` text only**, no schema change. Functionally identical to (a) + with a documentation convention layered on top. + +**Recommendation: (a)/(c) combined** β€” reuse `content`, and require +`behavioral_fingerprint` for these two records to state explicitly that the vulnerable +surface is the tool's *own implementation code*, not its declared instructions (both +draft fingerprints in #32/#33 already do this). Revisit as a real `(b)` schema-change +proposal only if a *third* code-implementation-vulnerability class shows up in a future +research pass β€” one overloaded bucket is a documentation note, three is a pattern that +earns its own enum value. This keeps the batch un-blocked and defers the schema question +until there's enough evidence to answer it well. + +**RESOLVED 2026-07-10:** adopted as written β€” `detection_layer: content` for #32 and +#33, `behavioral_fingerprint` states the implementation-code surface explicitly, no +schema change opened.

Recommend keeping it under `Tool Abuse` for this batch (least +taxonomy churn, and `attack_class` is free text, not an enum, so it costs nothing to +rename later without a schema change) rather than inventing a new top-level category for +one record.

The issue recommends the record state both +rather than picking one.

If +so, recommend `severity: HIGH` as the more conservative of the two (NIST's independent +assessment over the affected vendor's own CNA rating), with the AARF/`aivss.notes` field +carrying the Microsoft 9.3 figure as context.

Closest parent would be AVE-2026-00051 (OAuth Discovery Rebinding), but the mechanism is different (social-engineered consent redirect vs. tampered discovery metadata). Leaning **OUT OF SCOPE** per the same reasoning AVE already applies to model-layer ATLAS techniques, but flagging rather than deciding, since it sits closer to AVE's boundary than a clear-cut case. | + +--- + +## Phase 2 benchmarking detail β€” why each NEW CLASS candidate isn't already covered + +**#1 tool-implementation-command-injection vs. AVE-2026-00004 (Shell Pipe Injection) / AVE-2026-00033 (Unsafe Deserialization):** +00004 and 00033 both describe a skill's *natural-language content* instructing the agent +to construct and run a dangerous command β€” the vulnerability is in what the text tells +the LLM to do. CVE-2026-0755 is a classic CWE-78 flaw in the MCP *tool's own server-side +handler code* (`execAsync`): a crafted tool-call *parameter value* reaches an unsanitized +shell call with no LLM reasoning involved at all β€” a non-agentic attacker could trigger +it by sending a raw JSON-RPC request. Different mechanism, different detection method +(SAST/code review of server source vs. content-layer prompt scanning). Fails the "fold +it in and lose nothing" test β€” folding it into 00004 would erase the distinction between +prompt-driven misuse of a legitimate capability and a code-level injection bug in the +capability's own implementation. + +**#2 mcp-resource-path-traversal vs. AVE-2026-00022 (Scope Creep):** +00022 is content-layer: a skill's text instructs the agent to *ask for* out-of-scope +resources. The three path-traversal CVEs are CWE-22 flaws in a resource/file handler's +own path-validation logic, triggered by a parameter value regardless of any instruction +content. Same distinction as #1 β€” code vulnerability vs. prompt-driven overreach. + +**#3 mcp-stdio-launch-config-injection vs. AVE-2026-00001 (Metamorphic Payload) / AVE-2026-00034 (Dynamic Skill Import):** +Both existing records describe a component's *content* fetching or loading new +instructions at runtime β€” the LLM is still in the loop, executing instructions found in +fetched data. The STDIO flaw happens *before any protocol handshake or LLM reasoning*: +untrusted data in the `command`/`args` config fields used to spawn the MCP server +subprocess is executed directly by the OS. Confirmed via direct technical read +(penligent.ai) as explicitly distinct from prompt injection: "the attacker's goal may +not be to make the model say something unsafe... [it manipulates] the boundary between +configuration and process creation." + +**#4 rendered-content-autofetch-exfiltration vs. AVE-2026-00026 (Output Encoding) / AVE-2026-00039 (Covert Channel):** +This is the closest call. 00026 is exfiltration *through a tool call parameter*; 00039 +is steganographic *hiding* of data in visible output text for later decoding. EchoLeak's +mechanism needs neither: a plain, unobfuscated markdown image reference in the agent's +own answer is automatically fetched by the *client's rendering layer*, causing an +outbound request with no tool call and no encoding step. The distinguishing behavior is +"the answer itself is the beacon, and the renderer sends it for free." I believe this +clears the bar, but flagging the adjacency explicitly since it's the least clear-cut of +the five. + +**#5 code-execution-sandbox-escape vs. AVE-2026-00042 (REPL Code Mode Payload Injection):** +00042 is about how malicious code *gets into* the agent's generated code (data breaking +into code context via poisoned tool results). CVE-2026-5752 is about what happens *after* +code is already running inside an intended sandbox: a JavaScript prototype-chain +traversal breaks the isolation boundary to root-level host execution β€” a flaw in the +sandbox's own containment, exploitable even by code the agent was *authorized* to run. +Different point in the kill chain (content-to-code vs. code-to-host), different defense +(input/context separation vs. isolation hardening). + +--- + +## What I did not do + +Per the skill's hard rule 6 ("report and stop before implementing β€” never auto-create +records without confirmation") and the zoom-out protocol ("do not edit during +zoom-out"): no GitHub issues opened, no records/rules/fixtures created.

Not published. - ---- - -## What AVE is - -The behavioral classification standard for agentic AI components. -Relates to AST10/ASI the way CWE relates to OWASP Top 10 β€” a Top 10 names the -categories that matter; AVE supplies the individually-scored, individually- -detectable records underneath them. An open standard that bawbel-scanner -implements as its reference implementation. Not a feature of the scanner; an -independent asset with its own schema, registry, and community. - -AVE is Layer 1 of the Bawbel five-layer architecture. The open layers -(AVE standard + scanner) drive adoption and community trust. The proprietary -layers (PiranhaDB, registry, web platform) are the commercial moat. - ---- - -## Why it exists - -Existing vulnerability standards were built for conventional software. -CVE maps to CPE. OSV maps to package and version range. Neither can describe -a prompt injection hidden in an MCP tool description β€” there is no package, -no version, no vulnerable dependency. The threat is behavioral. The same -malicious behavior appears in infinitely many textual forms. - -AVE fills that gap: stable IDs, behavioral fingerprints, AIVSS scoring, -framework mappings, and detection rules β€” for the attack surface that the -package world cannot see. - -Do not frame AVE as "the CVE for AI agents" or "the CWE for AI agents." -Use own-terms framing: "the behavioral classification standard for agentic -AI components."

A full scan runs both: OSV for dependencies, AVE for agent -components. AVE originates net-new behavioral classes; OSV aggregates -existing package-level findings. - -Do not frame AVE as "OSV for AI agents" β€” OSV is an aggregator. AVE -is a classification standard.

That fragmentation is the AVE adoption argument: the field needs a -common reference, and AVE is it. - -The adoption path: -1.
