π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Pull request overview
Hardens the analysis engineβs local stem-separation path handling to mitigate path traversal risk from untrusted audio_path and model_profile_path inputs, and adds regression tests to validate the new behavior.
Changes:
- Added path traversal detection to reject
..components for both POSIX and Windows-style paths before resolving. - Added unit tests covering traversal rejection and ensuring
..inside filenames isnβt falsely blocked. - Documented the incident and prevention notes in the Sentinel log.

| File | Description |
|---|---|
| services/analysis-engine/src/bandscope_analysis/separation/audio_separator.py | Adds traversal-component checks for audio and model profile paths prior to resolution. |
| services/analysis-engine/tests/test_separation.py | Adds regression tests for traversal rejection (POSIX/Windows) and dot-containing filenames. |
| .jules/sentinel.md | Records the vulnerability/learning/prevention notes for the path traversal issue. |
π‘ Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
| **Vulnerability:** Untrusted paths passed from the frontend for `audio_path` and `model_profile_path` were processed using `Path().expanduser()` and lacked validation against path traversal components like `..`, potentially exposing arbitrary local files. | ||
| **Learning:** Functions like `os.path.expanduser` or `Path().expanduser()` should not be used with untrusted inputs. Path traversal validation (e.g., checking for `..` sequences) must be explicit when dynamically accessing paths. | ||
| **Prevention:** Strictly sanitize untrusted dynamic paths, remove `.expanduser()`, and explicitly validate inputs (e.g., `if ".." in str(path): raise ValueError(...)`) to prevent path traversal risks, followed by automated CI vulnerability scanners (like Strix) validation. |
