Overview
Affected versions of this package are vulnerable to Improper Input Validation when the client may bypass JSON Web Token (JWT) checks and forge fake original paths. The header x-envoy-original-path should be internal, but Envoy does not remove this header from the request at the beginning of request processing when it is sent from an untrusted client. The faked header would then be used for trace logs and grpc logs, as well as used in the URL used for jwt_authn checks if the jwt_authn filter is used, and any other upstream use of the x-envoy-original-path header.
