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\u2019s 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.\n\ud83d\udccf Published: 2025-04-21T15:34:04.637Z\n\ud83d\udccf Modified: 2025-04-21T15:55:15.087Z\n\ud83d\udd17 References:\n1. https://github.com/traefik/traefik/security/advisories/GHSA-6p68-w45g-48j7\n2. https://github.com/traefik/traefik/pull/11684\n3. https://github.com/traefik/traefik/releases/tag/v2.11.24\n4. https://github.com/traefik/traefik/releases/tag/v3.3.6\n5. https://github.com/traefik/traefik/releases/tag/v3.4.0-rc2", "creation_timestamp": "2025-04-21T16:02:50.000000Z"}
