CVE-2026-60291: Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Core).
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 HTTP 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).
Security readout for executives and security teams
Plain-English summary
A remote, unauthenticated attacker who can reach an affected WebLogic Server over HTTP may take complete control. That could expose sensitive data, permit unauthorized changes, and disrupt dependent applications. The combination of easy network exploitation and total confidentiality, integrity, and availability impact makes this a critical business risk.
Executive priority
Treat as an immediate remediation priority. Complete exposure discovery now, isolate reachable affected servers where practical, and apply Oracle's prescribed remediation under emergency change procedures. Systems processing sensitive information or supporting essential services should receive highest priority. Begin incident review if suspicious activity or unauthorized configuration changes are found.
Technical view
CVE-2026-60291 affects Oracle WebLogic Server Core versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. It is classified as CWE-306, indicating missing authentication for a critical function. The CVSS 3.1 score is 9.8: network-accessible, low complexity, no privileges or user interaction, with potential server takeover.
Likely exposure
Highest exposure exists where an affected WebLogic HTTP service is reachable from the internet or untrusted networks. Internally reachable systems also remain exposed to compromised hosts or unauthorized users. The supplied sources do not identify specific endpoints, configurations, or compensating controls that eliminate risk.
Exploitation context
The supplied record describes the vulnerability as easily exploitable and capable of unauthenticated takeover through HTTP. It is not identified as a CISA KEV entry in the bundle, and no cited source establishes active exploitation, public proof-of-concept availability, or observed campaigns. Absence from KEV does not prove exploitation is not occurring.
Researcher notes
The public bundle identifies CWE-306 but provides no vulnerable endpoint, protocol detail beyond HTTP, root cause, affected configuration conditions, or exploit telemetry. Researchers should avoid assuming all installations are equally reachable. Validation should focus on authoritative version identification, network accessibility, remediation state, and compromise indicators without attempting exploitation.
Mitigation direction
Identify every deployment running one of the four affected WebLogic versions.
Review and apply the remediation specified in Oracle's July 2026 advisory.
Restrict HTTP access to trusted networks until vendor remediation is confirmed.
Prioritize internet-facing and business-critical WebLogic systems for immediate treatment.
Check Oracle guidance for prerequisites, patch details, and any later updates.
Validation and detection
Confirm installed WebLogic versions using authoritative asset and deployment records.
Test whether affected HTTP services are reachable from internet and untrusted network segments.
Verify Oracle's prescribed remediation is installed on every affected instance.
Review logs for unexpected HTTP activity, administrative changes, or signs of server compromise.
Reassess network exposure after remediation and confirm temporary restrictions remain effective where needed.

Missing Authentication for Critical Function
Missing Authentication for Critical Function represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
