AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network SOAP request (AV:N/PR:N/UI:N) with low complexity yields full server takeover, so C:H/I:H/A:H; scope unchanged as compromise stays within the server.
Primary rating from Vendor (oracle).

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 SOAP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Remote takeover of Oracle WebLogic Server (Fusion Middleware Core component) allows an unauthenticated network attacker to fully compromise the server via a crafted SOAP request. 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 Oracle rates it easily exploitable with complete confidentiality, integrity, and availability impact (CVSS 9.8). No public exploit was identified at time of analysis, but given WebLogic's history as a mass-exploitation target, this warrants immediate patching from the July 2026 Critical Patch Update.
Technical ContextAI
Oracle WebLogic Server is a Java EE application server widely used to host enterprise web services and middleware. The flaw resides in the 'Core' component and is reached over the SOAP protocol, indicating the vulnerable code path is exposed through WebLogic's web-services/T3-adjacent SOAP handling layer. Oracle did not assign a CWE (listed as N/A), but the 'takeover' outcome combined with an unauthenticated SOAP entry point is consistent with WebLogic's well-documented pattern of insecure deserialization of untrusted Java objects delivered via SOAP/XML payloads, which historically yields remote code execution. The affected CPE is cpe:2.3:a:oracle_corporation:oracle_weblogic_server, spanning the 12.2.1.4, 14.1.1, 14.1.2, and 15.1.1 release lines.
RemediationAI
Patch available per vendor advisory: apply the fixes bundled in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html) to each affected release line (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0); an exact patched build number was not provided in the input and should be taken directly from the CPU advisory matrix for your version. Because Oracle CPU patches require downtime, if you cannot patch immediately, apply compensating controls: restrict network access to the WebLogic administrative and web-services ports (e.g., 7001/7002 and any custom SOAP listener ports) so they are reachable only from trusted management networks, and place the server behind a filtering reverse proxy or WAF that blocks or inspects untrusted SOAP/XML POST requests to the Core web-services endpoints. As a stronger mitigation consistent with prior WebLogic guidance, disable or firewall the T3/IIOP and unused web-service subsystems if they are not required, noting the trade-off that this can break legacy client integrations and remote management tooling that rely on those protocols. These controls reduce exposure but are not a substitute for the CPU patch.
