When ReplacePathRegex is configured with a regex that captures user-controlled path segments without a mandatory path separator (e.g. regex \"^/api(.*)\", replacement \"/$1\"), the middleware forwards the replaced path to the backend without validating that it matches its normalized form. An unauthenticated remote attacker can send a crafted request (e.g. GET /api../admin) that produces an un-normalized path such as /../admin, which a backend that normalizes paths resolves to a protected route, bypassing authentication middleware.
