CVE-2026-60527: 
Oracle WebLogic Server vulnerability analysis and mitigation

CVE-2026-60527 is a local information disclosure vulnerability in the Console component of Oracle WebLogic Server, part of Oracle Fusion Middleware. It affects supported versions 14.1.2.0.0 and 15.1.1.0.0. The vulnerability allows an unauthenticated attacker with local logon access to the infrastructure where WebLogic Server executes to compromise the server, with a scope change that may impact additional products. It carries a CVSS v3.1 base score of 7.1 (High) (Oracle CPU Jul 2026, Feedly).

The vulnerability resides in the Console component of Oracle WebLogic Server and is classified as a local attack vector (CWE details not explicitly published by Oracle). An unauthenticated attacker who has logon access to the host infrastructure can exploit this flaw without requiring any privileges or user interaction, and with low attack complexity. The scope change indicates that a successful exploit can affect resources beyond the WebLogic Server itself, potentially exposing data accessible to other co-located products or services (Oracle CPU Jul 2026).

Successful exploitation results in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data, representing a high confidentiality impact. There is no integrity or availability impact associated with this vulnerability. The scope change noted in the CVSS scoring means that sensitive data from additional products running on the same infrastructure may also be exposed (Oracle CPU Jul 2026, Feedly).

1. Gain local access: Obtain logon access to the host infrastructure where Oracle WebLogic Server 14.1.2.0.0 or 15.1.1.0.0 is running — this could be via a compromised OS account, shared hosting environment, or insider access.
2. Identify the Console component: Locate the WebLogic Administration Console endpoint on the target system, typically accessible at http://<host>:<port>/console.
3. Exploit the Console vulnerability: Interact with the vulnerable Console component without providing authentication credentials, leveraging the flaw to trigger unauthorized data access.
4. Exfiltrate sensitive data: Extract critical data accessible to the WebLogic Server process, which may include configuration files, credentials, or data from co-located products due to the scope change (Oracle CPU Jul 2026).

Oracle has addressed CVE-2026-60527 as part of the July 2026 Critical Patch Update (CPU). Administrators running Oracle WebLogic Server versions 14.1.2.0.0 or 15.1.1.0.0 should apply the relevant patches from the July 2026 CPU immediately. As a temporary risk reduction measure, Oracle recommends restricting local logon access to the infrastructure hosting WebLogic Server to only authorized personnel, though this is not a permanent fix. Oracle strongly advises against delaying patch application (Oracle CPU Jul 2026).
