CVE-2025-15381

In the latest version of mlflow/mlflow, when the `basic-auth` app is enabled, tracing and assessment endpoints are not protected by permission validators. This allows any authenticated user, including those with `NO_PERMISSIONS` on the experiment, to read trace information and create assessments for traces they should not have access to. This vulnerability impacts confidentiality by exposing trace metadata and integrity by allowing unauthorized creation of assessments. Deployments using `mlflow server --app-name=basic-auth` are affected.

Summary		(es) En la última versión de mlflow/mlflow, cuando la aplicación 'basic-auth' está habilitada, los puntos finales de trazado y evaluación no están protegidos por validadores de permisos. Esto permite a cualquier usuario autenticado, incluidos aquellos con 'NO_PERMISSIONS' en el experimento, leer información de trazas y crear evaluaciones para trazas a las que no deberían tener acceso. Esta vulnerabilidad afecta la confidencialidad al exponer metadatos de trazas y la integridad al permitir la creación no autorizada de evaluaciones. Las implementaciones que utilizan 'mlflow server --app-name=basic-auth' se ven afectadas.
