AnalysisAIv1 – Sep 02, 2026

LDAP injection in the Drupal LDAP / Active Directory Integration module (versions below 2.2.1) allows unauthenticated remote attackers to manipulate LDAP query structure by submitting unsanitized input containing LDAP special characters. The primary confirmed impact is partial confidentiality loss — directory enumeration or partial authentication bypass — with no integrity or availability impact per the CVSS vector. No public exploit code or CISA KEV listing has been identified at time of analysis, though the unauthenticated network-accessible attack vector makes it straightforward to attempt against exposed instances.
