{"id":"CVE-2026-55251","summary":"NetBox Device Type Library: Arbitrary Code Execution on CI Runner Through Malicious requirements.txt, .pre-commit-hooks-config.yaml, and .gitmodules Files","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.","aliases":["GHSA-5x2m-x42f-g4cm"],"modified":"2026-10-04T02:30:32.310359979Z","published":"2026-10-01T19:49:32.741Z","database_specific":{"cwe_ids":["CWE-494","CWE-829","CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55251.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"f41fc1e48dec8d7d31afba5f13a8c73652ff5796"}]}],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55251.json"},{"type":"ADVISORY","url":"https://github.com/netbox-community/devicetype-library/security/advisories/GHSA-5x2m-x42f-g4cm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55251"},{"type":"FIX","url":"https://github.com/netbox-community/devicetype-library/commit/f41fc1e48dec8d7d31afba5f13a8c73652ff5796"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/netbox-community/devicetype-library","events":[{"introduced":"0"},{"fixed":"f41fc1e48dec8d7d31afba5f13a8c73652ff5796"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55251.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
