Affected: authlib, Red Hat Ansible Automation Platform 2.6, Red Hat Quay 3.10, Red Hat Quay 3.12, Red Hat Quay 3.15, Red Hat Quay 3.16, Red Hat Quay 3.9, Red Hat Satellite 6

Authlib is a Python library which builds OAuth and OpenID Connect servers. From version 1.6.5 to before version 1.6.7, previous tests involving passing a malicious JWT containing alg: none and an empty signature was passing the signature verification step without any changes to the application code when a failure was expected.. This issue has been patched in version 1.6.7.
