Description OSIDB Bzimport 2026-10-26 15:32:47 UTC 
**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.
