CVE-2026-115748: Apache Vysper: Authorization bypass

Severity: important 
    CVSS 3.1: 8.8 (high) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Affected versions:

- Apache Vysper: all versions

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.
