Technical details

A vulnerability exists in the OUD Core component of Oracle Unified Directory (versions 12.2.1.4.0 and 14.1.2.1.0). The flaw is easily exploitable by a low-privileged attacker with network access via the LDAP protocol. Successful exploitation results in a 'scope change' (S:C), meaning the impact can extend beyond the directory service itself to other products in the environment. Attackers can achieve unauthorized read access to all directory data and perform unauthorized updates, inserts, or deletions of certain data records. The vulnerability was disclosed as part of the Oracle Critical Patch Update for July 2026.
