Traefik: Authentication Bypass via Path Traversal in ReplacePathRegex Middleware...

CVE-2026-65600

A flaw was found in Traefik. An unauthenticated remote attacker can bypass authentication due to a path traversal vulnerability in the ReplacePathRegex middleware. When this middleware is misconfigured, it forwards un-normalized paths, allowing a backend to resolve them to protected routes and...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the ServeHTTP function in pkg/middlewares/replacepathregex/replacepathregex.go, which forwards the post-substitution path to the backend without checking whether it normalizes to a different route. An attacker can...
