Project: LDAP / Active Directory Integration [1]
Date: 2026-August-26
Security risk: *Moderately critical* 14 ∕ 25
AC:Basic/A:None/CI:Some/II:None/E:Proof/TD:All [2]
Vulnerability: Information Disclosure

Affected versions: <2.2.1
CVE IDs: CVE-2026-81205
Description: 
This module enables users to authenticate using LDAP or Active Directory
credentials.

The module does not sufficiently sanitize user-supplied input before
incorporating it into an LDAP search filter. This allows an attacker to
discover additional information they should not normally be able to.

Solution: 
Install the latest version:

 * If you use the LDAP / Active Directory Integration module, upgrade to LDAP
   / Active Directory Integration 2.2.1 [3].
