Summary

GHSA-3ww4-5jv9-j5gm reports that vLLM's revision pinning does not consistently cover all artifacts loaded for a model. Deployments that set `--revision` or `--code-revision` can still load dynamic code, GGUF files, image processors, retrieval side weights, or same-repository subfolder weights and config from an unpinned or default revision, so the pin does not describe the full artifact set served. The source states this is not a `trust_remote_code=False` bypass, unauthenticated RCE, or a demonstrated artifact compromise. The strongest example is Kimi-Audio, whose `whisper-large-v3` subfolder loads outside the configured revision.
