2DescriptionCVE.org
Vulnerability in the Oracle Unified Directory product of Oracle Fusion Middleware (component: OUD Core). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via LDAP to compromise Oracle Unified Directory. While the vulnerability is in Oracle Unified Directory, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Unified Directory accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).
AnalysisAI
Oracle Unified Directory (OUD) versions 12.2.1.4.0 and 14.1.2.1.0 expose a network-accessible LDAP authorization bypass that enables a low-privileged authenticated attacker to gain unauthorized access to critical or complete directory data. Intelligence sources tag this as an authentication bypass in the OUD Core component, with confirmed scope change impact on additional Oracle Fusion Middleware products consuming OUD identity data. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) a valid low-privileged LDAP credential for the target OUD instance, confirmed by the CVSS PR:L metric - unauthenticated external attackers cannot exploit this directly without first obtaining an account through other means; (2) network access to the OUD LDAP service endpoint (AV:N), typically TCP port 389 or 636, which may be exposed internally or, in misconfigured deployments, externally; (3) one of the two confirmed vulnerable versions: 12.2.1.4.0 or 14.1.2.1.0. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.7 (High) accurately reflects meaningful real-world risk: the attack vector is network-based LDAP (AV:N), complexity is low (AC:L), no user interaction is required (UI:N), and the scope change (S:C) amplifies organizational impact in integrated Oracle environments. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the patches released in Oracle's August 2026 Critical Patch Update (CPU), available at https://www.oracle.com/security-alerts/cspuaug2026.html, targeting Oracle Unified Directory versions 12.2.1.4.0 and 14.1.2.1.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and document all Oracle Unified Directory deployments running versions 12.2.1.4.0 or 14.1.2.1.0, and map which Fusion Middleware applications depend on each OUD instance for identity services. …
