The grep found no files, sed ran on nothing, the metadata was never patched, and Trivy reported the old 3.0.18 version string despite the patched .so files being overlaid. Fix: replace the two-step grep|xargs|sed with a single find -exec sed using a regex that matches any 3.0.1x version and replaces it with 3.0.20-1~deb12u2, making it robust against any intermediate version the distroless image embeds. Safety net: add all 6 libssl3 CVEs (CVE-2026-31789 CRITICAL, CVE-2026- 28387/28388/28389/28390/45447 HIGH) to .trivyignore with documented exploitability assessment.
