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.
