This issue was patched in RHSA-2026:64784.

NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base-libs package and not the 389-ds-base-libs package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user.
