Advisory
Source description from Wordfence Intelligence, credited to Luca Greeb, Andreas Krüger.
The Active Directory Integration / LDAP Integration plugin for WordPress is vulnerable to LDAP Injection in versions up to, and including, 4.1.5. This is due to insufficient escaping on the supplied username value. This makes it possible for attackers, with an existing account on a vulnerable WordPress instance, to extract potentially sensitive information from the LDAP directory.
