CVE-2026-47155 – vLLM: Artifact Pin Decay in vLLM allows pinned deployments to load unpinned code, weights, and processors

CVE ID :CVE-2026-47155

Published : June 22, 2026, 10:20 p.m. | 1 hour, 23 minutes ago

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.

Severity: 0.0 | NA
