Unauthenticated LDAP data tampering and service interruption
Published Jun 16, 2026 · Updated Jun 16, 2026
Improper access control in Oracle Unified Directory 12.2.1.4.0 and 14.1.2.1.0 allows remote attackers to alter directory data via LDAP. Oracle identifies OUD Core but has not disclosed the faulty access-control operation or LDAP request that triggers it. No credentials or user interaction are required; successful exploitation permits partial reads, broad creation, deletion, or modification, and a partial service interruption.
