During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority without any valid credentials. A variant using a valid low-privileged account's own successful bind instead of an anonymous one is also possible.","state":0,"publishedAt":"2026-09-07T14:14:53.799+00:00","modifiedAt":"2026-10-08T14:14:57.932+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"redhat-ds:11","ranges":[],"versions":[],"rawVersionEvidence":"{\n
