Upstream source description

**UNSUPPORTED WHEN ASSIGNED**  Authorization bypass in Apache Vysper, all versions. Apache Vysper is an XMPP (Jabber) server library. Its XEP-0077 (In-Band Registration) implementation is missing an authentication check, allowing any authenticated user to compromise other accounts. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative.
