Description Avinash Hanwate 2022-05-20 11:39:03 UTC

The OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current implementation assumes that access tokens are always
validated thus allowing access in the presence of any access token attached to the request.
