Estos flags se pasan directamente al servidor de inferencia subyacente (llama.cpp). Al inyectar el flag --log-file, un atacante con acceso de red a la API de Model Runner puede escribir o sobrescribir archivos arbitrarios accesibles para el proceso de Model Runner. Cuando se incluye con Docker Desktop (donde Model Runner est\u00e1 habilitado por defecto desde la versi\u00f3n 4.46.0), es accesible desde cualquier contenedor predeterminado en model-runner.docker.internal sin autenticaci\u00f3n.

An attacker who can reach the endpoint can inject arbitrary flags \u2013 for example --log-file \u2013 causing the underlying inference server to create or overwrite files that are accessible to the Model Runner process.

The vulnerability is not listed in the CISA KEV catalog. An attacker only needs network access to the Model Runner API; the flaw is unauthenticated, making it straightforward to craft requests. The attacker can overwrite critical files such as Docker.raw, causing loss of all Docker data, or in specific setups perform a container escape. The presence of an exposed TCP endpoint further increases the attack surface."}}}}, "created": "2026-03-02T12:04:51.322850+00:00", "updated": "2026-04-16T15:15:39.051046+00:00", "vendors": ["docker", "docker$PRODUCT$model-runner"]}
