Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

vLLM versions from 0.22.1 through 0.28.0 do not apply the operator's model revision pin to some Hugging Face artifact loads for the FunAudioChat and Tarsier2 architectures. Processor, tokenizer, and config files for these models can be fetched from the repository's default branch, so an upstream change can alter behavior even when a reviewed revision is pinned. The source describes this as a reproducibility and supply-chain integrity issue, not remote code execution. Upgrade vLLM to version 0.28.0 or later.
