Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: Jenkins Project

Description
Jenkins Active Directory Plugin 2.41.1 and earlier does not escape the user name before building the LDAP search filter in the Windows native (ADSI) authentication path, allowing unauthenticated attackers to inject LDAP wildcard characters to enumerate directory entries and to authenticate as a matching user whose password they know without knowing their exact user name.

Executive Summary

The vulnerability exists in Jenkins Active Directory Plugin version 2.41.1 and earlier. It occurs because the plugin does not properly escape the user name before constructing the LDAP search filter in the Windows native (ADSI) authentication path.

This flaw allows unauthenticated attackers to inject LDAP wildcard characters, which can be used to enumerate directory entries and potentially authenticate as a matching user if the attacker knows that user's password, even without knowing the exact user name.

Impact Analysis

This vulnerability can impact you by allowing unauthenticated attackers to gather information about directory entries through LDAP wildcard injection.

Additionally, attackers may be able to authenticate as a user whose password they know without needing to know the exact user name, potentially leading to unauthorized access.
