CVE-2023-3447Network attack vector

Directory data disclosure via unescaped LDAP username

Published Jun 29, 2023 · Updated Apr 8, 2026

LDAP injection in miniOrange LDAP / Active Directory Integration 4.1.5 and earlier allows remote authenticated users to read directory data. The LDAP authentication path inserts the supplied WordPress username into a directory query without sufficient escaping, allowing LDAP metacharacters to alter the filter. An existing WordPress account is required, and the altered query can extract sensitive information from the configured LDAP directory.
