CVE-2026-111261

Published Nov 10, 2026 CWE-287

Description

The Jakarta Security LDAP identity store accepts an empty password as valid if the directory server allows unauthenticated binds, which some directory servers do by default. A remote attacker can then authenticate as any existing user without knowing the password. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
