CVE-2025-47952

Traefik (pronounced traffic) is an HTTP reverse proxy and load balancer. Prior to versions 2.11.25 and 3.4.1, there is a potential vulnerability in Traefik managing the requests using a PathPrefix, Path or PathRegex matcher. When Traefik is configured to route the requests to a backend using a matcher based on the path, if the URL contains a URL encoded string in its path, it’s possible to target a backend, exposed using another router, by-passing the middlewares chain. This issue has been patched in versions 2.11.25 and 3.4.1.

Summary		(es) Traefik (pronunciado "traffic") es un proxy inverso HTTP y balanceador de carga. En versiones anteriores a la 2.11.25 y la 3.4.1, existía una vulnerabilidad potencial en Traefik al gestionar las solicitudes mediante un comparador PathPrefix, Path o PathRegex. Cuando Traefik se configura para enrutar las solicitudes a un backend mediante un comparador basado en la ruta, si la URL contiene una cadena codificada, es posible atacar un backend expuesto mediante otro enrutador, omitiendo la cadena de middleware. Este problema se ha corregido en las versiones 2.11.25 y la 3.4.1.
