The validation test harness can deserialize pull-request-controlled tracked pickle cache files through pickle.load in the read_pickle_data function in tests/pickle_operations.py. An unauthenticated contributor can change USE_LOCAL_KNOWN_SLUGS in tests/test_configuration.py and supply a crafted tests/known-modules.pickle or tests/known-racks.pickle file that tests/definitions_test.py loads when pytest runs. Deserialization invokes attacker-controlled object reduction behavior, allowing arbitrary code execution in the GitHub Actions runner or in a maintainer process that runs the tests, with the confidentiality, integrity, and availability of reachable resources at risk. This vulnerability is fixed with commit 1c6f7e2b93589b965318c6e67ac3504831f0e71e.","published":"2026-09-17T20:16:52.877","modified":"2026-09-17T20:16:52.877","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/netbox-community/devicetype-library/commit/1c6f7e2b93589b965318c6e67ac3504831f0e71e","label":"netbox-community/devicetype-library@1c6f7e2"},"references":[{"type":"WEB","url":"https://github.com/netbox-community/devicetype-library/commit/1c6f7e2b93589b965318c6e67ac3504831f0e71e"},{"type":"WEB","url":"https://github.com/netbox-community/devicetype-library/pull/4238"},{"type":"WEB","url":"https://github.com/netbox-community/devicetype-library/security/advisories/GHSA-492p-5wp7-2w7c"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T20:16:52.877"}}
