Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via T3, IIOP to compromise Oracle WebLogic Server. While the vulnerability is in Oracle WebLogic Server, 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 WebLogic Server accessible data. CVSS 3.1 Base Score 8.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).
AnalysisAI
Unauthenticated remote data disclosure in Oracle WebLogic Server Core allows network-accessible attackers to exfiltrate all data reachable by the server via the T3 or IIOP protocols, with confirmed scope change impact on additional downstream systems. Tagged as an Authentication Bypass by Oracle, this affects four active release lines - 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 - making it a broad exposure across the WebLogic installed base. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The T3 or IIOP protocol listener must be reachable from the attacker's network position - these are enabled by default in WebLogic and typically listen on port 7001 (HTTP/T3) or 7002 (HTTPS/T3S). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N reflects an extremely accessible attack profile: fully unauthenticated, low complexity, no user interaction, reachable over the network. … 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 Oracle's Critical Patch Update (CPU) for August 2026, available via the Oracle Security Alerts portal at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Oracle WebLogic Server instances running versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0 and classify by criticality and network exposure. …
