  "details": "NetBox Device Type Library is a collection of community-sourced device type definitions for import into NetBox. 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.",
