In versions from 0.22.1 through 0.28.0, the operator-supplied model revision pin (--revision / --code-revision) is not propagated to several Hugging Face artifact loads for the FunAudioChat and Tarsier2 architectures: the WhisperFeatureExtractor and speech_tokenizer PreTrainedTokenizerFast loads in vllm/model_executor/models/funaudiochat.py and the Qwen2VLConfig.from_pretrained call used by Tarsier2ProcessingInfo in vllm/model_executor/models/qwen2_vl.py. As a result, deployments pinned to a reviewed revision still resolve these behavior-affecting processor, tokenizer, and config artifacts from the repository's default revision, so a later change to the upstream default branch can alter audio preprocessing, speech tokenizer behavior, or Tarsier2 configuration without any change to the operator's configured pin. This is a supply-chain integrity and reproducibility failure for pinned deployments; it is residual to the earlier fix tracked as GHSA-3ww4-5jv9-j5gm / CVE-2026-47155 and does not constitute remote code execution or a trust_remote_code=False bypass. The issue is fixed in version 0.28.0.","state":0,"publishedAt":"2026-09-26T13:23:22.605+00:00","modifiedAt":"2026-10-01T11:06:45.139+00:00","affected":[{"ecosystem":"Vendor product","name":"vllm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vllm-project\",\n                    \"product\": \"vllm\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/vllm\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.22.1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.28.0\"\n                        },\n                        {\n                            \"version\": \"0.28.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.3,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-hhv2-872h-628q","https://github.com/vllm-project/vllm/commit/d26a28ab033697f55a1414b5b0435de7cd6045b6","https://www.vulncheck.com/advisories/vllm-0.22.1-before-0.28.0-incomplete-artifact-pin-propagation"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100653","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100653","identifiers":["CVE-2026-100653"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
