Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
vLLM versions 0.7.3 up to, but not including, 0.31.0 let a request's mm_processor_kwargs.code_revision select a different revision of a model's processor code when trust_remote_code is enabled. An attacker who controls a revision in the served model repository and can send multimodal requests could execute arbitrary code in the vLLM API process. Upgrade to vLLM 0.31.0 or later.
