Hi,

The following vulnerability was published for 389-ds-base.

CVE-2026-18922[0]:
| A flaw was found in 389 Directory Server. 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.


If you fix the vulnerability please also make sure to include the
