## 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 categorized by a scope change (S:C), meaning an exploit can impact components beyond the immediate security scope of the OUD Core. An attacker with low-privileged credentials can exploit this vulnerability over the network via the LDAP protocol. Successful exploitation can lead to unauthorized read access to all directory data (Confidentiality: High) and unauthorized modification, insertion, or deletion of certain data (Integrity: Low). Users are advised to refer to the Oracle Critical Patch Update for July 2026 for remediation guidance.
