CVE-2026-76560

Name of the Vulnerable Software and Affected Versions 389 Directory Server (affected versions not specified)

Description The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value. This allows an unauthenticated client to satisfy access control checks that were intended to require a matching authenticated identity. Consequently, an anonymous LDAP client can perform unauthorized operations, such as adding or modifying a directory entry, which a SELFDN-based ACI (Access Control Instruction) intended to restrict to a specific authenticated user.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
