CVE-2025-54864

Hydra is a continuous integration service for Nix based projects. Prior to commit f7bda02, /api/push-github and /api/push-gitea are called by the corresponding forge without HTTP Basic authentication. Both forges do however feature HMAC signing with a secret key. Triggering an evaluation can be very taxing on the infrastructure when large evaluations are done, introducing potential denial of service attacks on the host running the evaluator. This issue has been patched by commit f7bda02. A workaround involves blocking /api/push-github and /api/push-gitea via a reverse proxy.

Summary		(es) Hydra es un servicio de integración continua para proyectos basados en Nix. Antes del commit f7bda02, la forja correspondiente invocaba /api/push-github y /api/push-gitea sin autenticación HTTP básica. Sin embargo, ambas forjas sí incluyen firma HMAC con una clave secreta. Activar una evaluación puede ser muy exigente para la infraestructura cuando se realizan evaluaciones extensas, lo que puede generar ataques de denegación de servicio en el host que ejecuta el evaluador. Este problema se ha corregido con el commit f7bda02. Una solución alternativa consiste en bloquear /api/push-github y /api/push-gitea mediante un proxy inverso.
