CVE-2026-115748
**UNSUPPORTED WHEN ASSIGNED** Authorization bypass in Apache Vysper, all versions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unscored. Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
