Summary
CVE-2026-60696 is a critical vulnerability in the Core component of Oracle WebLogic Server (part of Oracle Fusion Middleware) that allows a remote, unauthenticated attacker to fully compromise the server. Oracle rates it as easily exploitable over the network via the T3 or IIOP protocols, with no privileges or user interaction required. Successful exploitation results in complete takeover of the affected WebLogic Server instance.
Technical details
- Root cause: A flaw in the WebLogic Server Core component that can be triggered through the server’s own protocol handlers rather than through the HTTP web tier.
- Trigger conditions: An attacker only needs network access to the WebLogic Server’s T3 or IIOP listener ports; no authentication or user interaction is needed.
- Attack vector: Network-based (AV:N), low attack complexity (AC:L), delivered via the T3 or IIOP protocols used for WebLogic’s RMI/EJB communication.
- Impact: Full compromise of confidentiality, integrity, and availability — described by Oracle as resulting in takeover of the WebLogic Server.
Affected software
- Oracle WebLogic Server 12.2.1.4.0
- Oracle WebLogic Server 14.1.1.0.0
- Oracle WebLogic Server 14.1.2.0.0
- Oracle WebLogic Server 15.1.1.0.0
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the patch for CVE-2026-60696 issued in Oracle’s August 2026 Critical Patch Update (Security Alert), updating affected WebLogic Server 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 installations to the fixed release Oracle provides for this advisory.
- If immediate patching is not possible: Restrict network access to the T3 and IIOP protocols/ports so they are not reachable from untrusted networks or the public internet, and disable these protocols on WebLogic channels where they are not required, until patching can be completed.
