Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Archiva versions up to and including 2.2.10 are affected. The source says that the setting to disable user registration can be bypassed, so an attacker can register an account even when registration is meant to be disabled. The source gives few details beyond this. No fix is listed, as the project has been retired, so the source recommends migrating to a different solution or isolating the instance from untrusted users.
