CVE-2026-46848: 
Oracle WebLogic Server vulnerability analysis and mitigation

CVE-2026-46848 is an Improper Access Control vulnerability (CWE-284) in the Console component of Oracle WebLogic Server, part of Oracle Fusion Middleware. It affects versions 14.1.2.0.0 and 15.1.1.0.0. The vulnerability was published on June 17, 2026, with a patch made available on June 18, 2026, as part of Oracle's June 2026 Critical Security Patch Update. It carries a CVSS v3.1 base score of 7.9 (High) (Oracle Advisory, NVD).

The vulnerability is classified under CWE-284 (Improper Access Control) and resides in the WebLogic Server Console component. The attack vector is local (AV:L), requiring a low-privileged attacker with logon access to the infrastructure where WebLogic Server executes. Exploitation also requires human interaction from a person other than the attacker (e.g., a social engineering or UI-redressing scenario), and successful exploitation results in a scope change — meaning impacts can extend beyond the WebLogic Server itself to additional products. No public proof-of-concept or detailed technical write-up has been disclosed (Oracle Advisory, NVD).

Successful exploitation allows a low-privileged local attacker to achieve high confidentiality and integrity impacts against WebLogic Server and potentially other products within scope. Specifically, an attacker can gain unauthorized read access to critical or all WebLogic Server-accessible data, as well as unauthorized creation, deletion, or modification of critical data. Availability is not impacted. The scope change indicates that compromise of WebLogic Server could cascade to dependent systems or services (Oracle Advisory, NVD).

Oracle released a patch for CVE-2026-46848 on June 18, 2026, as part of the June 2026 Critical Security Patch Update (CSPU). Affected versions are WebLogic Server 14.1.2.0.0 and 15.1.1.0.0; administrators should apply the available security patch immediately. As interim measures, Oracle recommends restricting local logon access to systems running WebLogic Server to authorized personnel only, implementing access controls on the WebLogic Server Console, and monitoring for suspicious local activity or unauthorized data access and modification attempts. Oracle strongly advises against relying on workarounds as a long-term solution (Oracle Advisory).
