      "value": "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."

      "value": "vLLM es un motor de inferencia y servicio para modelos de lenguaje grandes (LLM). Antes de la versión 0.22.0, los controles de fijación de revisión de vLLM no se aplican consistentemente a todos los artefactos cargados para un modelo. Una implementación que suministra --revision o --code-revision aún puede cargar código dinámico, archivos GGUF, procesadores de imágenes, pesos laterales de recuperación o pesos/configuración de subcarpetas del mismo repositorio desde una revisión no fijada/predeterminada. Esto es un problema de integridad de la cadena de suministro para las implementaciones de vLLM fijadas. Los operadores pueden creer que están sirviendo una revisión de modelo revisada mientras vLLM resuelve artefactos anidados o hermanos que afectan el comportamiento fuera de esa revisión revisada. Esta vulnerabilidad está corregida en la versión 0.22.0."
