Prior to commit f41fc1e, the CI workflow .github/workflows/validation.yml runs on pull_request and executes code supplied by the pull request before any maintainer review. Three PR-editable files drive this: \"requirements.txt\", \".pre-commit-hooks-config.yaml\" / \".pre-commit-yamlfmt-config.yaml\", and \".gitmodules\". A contributor with no special repository access could open a pull request that modifies these files and have their code run on the CI runner. This issue has been patched via commit f41fc1e.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":216079,"id":"CVE-2026-55251","ts":1791236101314,"field":"exploit_available","old":"false","new":"true"}]}
