2DescriptionCVE.org
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 low privileged 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 takeover of Oracle WebLogic Server. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
AnalysisAI
Remote takeover of Oracle WebLogic Server is possible when a low-privileged attacker reaches the server over the T3 or IIOP protocols, abusing a flaw in the Core component to fully compromise the host. Supported versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 are affected, and because the attack carries a scope change it can significantly impact products beyond WebLogic itself. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to Oracle WebLogic Server's T3 or IIOP listener (commonly TCP 7001/7002) and low-level privileges on the target (CVSS PR:L), with no user interaction needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine top-priority issue rather than an inflated high-CVSS score: the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H combines network reachability, low attack complexity, no user interaction, only low privileges required, full confidentiality/integrity/availability loss, and a scope change that lets impact spread beyond WebLogic. … 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 fixes from Oracle's August 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cspuaug2026.html) for your specific branch - 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 or 15.1.1.0.0; Patch available per vendor advisory, though the exact patched build numbers are not enumerated in the provided data and should be taken directly from the CPU matrix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory 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 immediately restrict network access to T3 (port 7001) and IIOP (port 7002) protocols from external and untrusted networks. …
