{"cve":"CVE-2026-47155","nvd":{"published":"2026-06-22T23:16:30.357","modified":"2026-10-25T23:10:00.167","status":"Analyzed","description":"vLLM is an inference and serving engine for large language models (LLMs). Prior to 0.22.0, vLLM's revision pinning controls do not consistently apply to all artifacts loaded for a model. A deployment that supplies --revision or --code-revision can still load dynamic code, GGUF files, image processors, retrieval side weights, or same-repository subfolder weights/config from an unpinned/default revision. This is a supply-chain integrity issue for pinned vLLM deployments. Operators can believe they are serving a reviewed model revision while vLLM resolves behavior-affecting nested or sibling artifacts outside that reviewed revision. This vulnerability is fixed in 0.22.0.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-345"],"references":["https://github.com/vllm-project/vllm/commit/d26a28ab033697f55a1414b5b0435de7cd6045b6","https://github.com/vllm-project/vllm/pull/42616","https://github.com/vllm-project/vllm/security/advisories/GHSA-3ww4-5jv9-j5gm","https://huntr.com/bounties/3f1e24c0-87d2-4f6c-a705-820f380879ac"],"products":["vllm:vllm"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-47155","score":0.00249,"percentile":0.16114,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3ww4-5jv9-j5gm","url":"https://osv.dev/vulnerability/GHSA-3ww4-5jv9-j5gm","summary":"vLLM's Artifact Pin Decay allows pinned deployments to load unpinned code, weights, and processors","modified":"2026-09-10T03:50:55.315232512Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.22.0"],"fixed":["0.22.0"]}]},{"id":"PYSEC-2026-2301","url":"https://osv.dev/vulnerability/PYSEC-2026-2301","summary":"","modified":"2026-07-13T07:15:12.555153958Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.22.0"],"fixed":["0.22.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
