In versions prior to 2.11.24, 3.3.6, and 3.4.0-rc2. 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 /../ 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 2.11.24, 3.3.6, and 3.4.0-rc2. A workaround involves adding a `PathRegexp` rule to the matcher to prevent matching a route with a `/../` in the path."},{"lang":"es","value":"Traefik (pronunciado \"traffic\") es un proxy inverso HTTP y balanceador de carga.
