      "value": "vLLM is an inference and serving engine for large language models (LLMs). Prior to 0.22.1, the vLLM Dockerfile is vulnerable to a dependency confusion attack through the flashinfer-jit-cache package. The package is installed from a custom index (flashinfer.ai/whl/) using --extra-index-url, but the package name was not registered on PyPI, and UV_INDEX_STRATEGY=\"unsafe-best-match\" is set globally. An attacker who registers flashinfer-jit-cache on PyPI with version 0.6.11.post2 can execute arbitrary code as root during the Docker build and backdoor every resulting container image, enabling exfiltration of all user prompts, API credentials, and model data from production vLLM deployments This vulnerability is fixed in 0.22.1."

      "value": "vLLM es un motor de inferencia y servicio para modelos de lenguaje grandes (LLMs). Antes de la versión 0.22.1, el Dockerfile de vLLM es vulnerable a un ataque de confusión de dependencias a través del paquete flashinfer-jit-cache. El paquete se instala desde un índice personalizado (flashinfer.ai/whl/) usando --extra-index-url, pero el nombre del paquete no estaba registrado en PyPI, y UV_INDEX_STRATEGY=’unsafe-best-match’ está configurado globalmente. Un atacante que registre flashinfer-jit-cache en PyPI con la versión 0.6.11.post2 puede ejecutar código arbitrario como root durante la compilación de Docker y establecer una puerta trasera en cada imagen de contenedor resultante, lo que permite la exfiltración de todas las indicaciones de usuario, credenciales de API y datos del modelo de las implementaciones de vLLM en producción. Esta vulnerabilidad se corrige en la versión 0.22.1."
