CVE-2026-60527 Overview
CVE-2026-60527 affects the Console component of Oracle WebLogic Server, part of Oracle Fusion Middleware. The flaw impacts supported versions 14.1.2.0.0 and 15.1.1.0.0. An unauthenticated attacker with logon access to the infrastructure where Oracle WebLogic Server executes can exploit this vulnerability. Successful exploitation results in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data. The vulnerability includes a scope change, meaning attacks may impact additional products beyond WebLogic Server itself. Oracle addressed the issue in the July 2026 Critical Patch Update.
Critical Impact
Local attackers can obtain unauthorized access to sensitive WebLogic Server data with impact extending to adjacent products through scope change.
Affected Products
- Oracle WebLogic Server 14.1.2.0.0
- Oracle WebLogic Server 15.1.1.0.0
- Oracle Fusion Middleware (Console component)

Technical Details for CVE-2026-60527
Vulnerability Analysis
The vulnerability resides in the Console component of Oracle WebLogic Server. An attacker who already has logon access to the infrastructure where WebLogic Server runs can exploit the flaw without authenticating to the application itself. Exploitation requires low attack complexity and no user interaction. The scope change indicator signals that a successful attack crosses trust boundaries, allowing impact to reach resources beyond the vulnerable component. The confidentiality impact is high, while integrity and availability are unaffected.
Root Cause
Oracle has not published detailed root cause information for CVE-2026-60527. The advisory places the defect inside the WebLogic Server Console component and confirms that access to WebLogic-managed data is exposed to a local, unauthenticated actor. For technical specifics, refer to the Oracle Critical Patch Update July 2026.
Attack Vector
The attack vector is local. An attacker requires a foothold on the host or adjacent infrastructure where WebLogic Server executes. From that position, the attacker interacts with the Console component to reach data that should be protected. No credentials are required for the WebLogic application, and no user interaction is needed. The scope change allows the impact to extend into other products that trust WebLogic Server. EPSS data lists an exploit probability of 0.162%.
Detection Methods for CVE-2026-60527
Indicators of Compromise
- Unexpected local process interactions with WebLogic Console endpoints or the AdminServer process
- Access to WebLogic configuration files, credential stores, or serialized data by non-administrative local accounts
- New or unrecognized local logons on hosts running WebLogic Server versions 14.1.2.0.0 or 15.1.1.0.0
Detection Strategies
- Inventory all Oracle Fusion Middleware deployments and identify hosts running affected WebLogic Server versions
- Alert on local process access to WebLogic domain directories such as $DOMAIN_HOME/config and $DOMAIN_HOME/servers
- Correlate local logon events with subsequent Console component activity or Java process spawning
Monitoring Recommendations
- Forward WebLogic AdminServer.log and access logs to a centralized log platform for anomaly review
- Monitor for reads of credential files including boot.properties and SerializedSystemIni.dat
- Track privilege changes and unexpected shell activity on WebLogic hosts
How to Mitigate CVE-2026-60527
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update to all affected WebLogic Server instances
- Restrict local logon rights on WebLogic hosts to a minimal set of administrators
- Audit existing local accounts and remove stale or unused entries
- Verify network segmentation so WebLogic hosts are not accessible from general-purpose user networks
Patch Information
Oracle released fixes as part of the Oracle Critical Patch Update July 2026. Administrators should download the patches corresponding to WebLogic Server 14.1.2.0.0 and 15.1.1.0.0 from My Oracle Support and follow the documented installation procedure for each affected domain.
Workarounds
- Disable the WebLogic Server Administration Console if it is not required in production, per Oracle's hardening guidance
- Enforce host-based access controls that limit interactive logons to WebLogic servers
- Isolate WebLogic infrastructure using jump hosts and privileged access management controls
# Example: restrict interactive logon to WebLogic administrators on Linux
sudo groupadd weblogic-admins
sudo usermod -aG weblogic-admins <admin_user>
# /etc/security/access.conf
# -:ALL EXCEPT root weblogic-admins:LOCAL
