HIGH 8.1

DescriptionCVE.org

Vulnerability in the Oracle WebCenter Sites product of Oracle Fusion Middleware (component: WebCenter Sites). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Sites. Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Sites. CVSS 3.1 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

AnalysisAI

Full compromise of Oracle WebCenter Sites (Fusion Middleware) is possible over the network by an unauthenticated attacker via HTTP, resulting in complete product takeover with high confidentiality, integrity, and availability impact. Supported versions 12.2.1.4.0 and 14.1.2.0.0 are affected, and Oracle addresses it in the July 2026 Critical Patch Update. The high attack complexity (AC:H) tempers real-world risk, and there is no public exploit identified at time of analysis and no CISA KEV listing.

Technical ContextAI

Oracle WebCenter Sites is an enterprise web experience management (WEM) and content management platform within the Oracle Fusion Middleware stack, used to author, manage, and deliver public-facing websites and digital content. The vulnerability resides in the core 'WebCenter Sites' component and is reachable over HTTP, meaning the exposed web-tier application (typically deployed on WebLogic Server) is the attack surface. No CWE was assigned in the source data, so the precise root-cause class (e.g., deserialization, authentication bypass, or injection) cannot be confirmed from the available intelligence; Oracle's tag of 'Information Disclosure' is narrower than the CVSS profile, which indicates full C/I/A takeover rather than mere disclosure.

RemediationAI

Apply the fixes in the Oracle July 2026 Critical Patch Update (Vendor-released patch per Oracle CPU July 2026) for the affected 12.2.1.4.0 and 14.1.2.0.0 branches; the advisory and patch matrix are at https://www.oracle.com/security-alerts/cpujul2026.html - an exact fixed build number was not included in the source data, so consult the CPU matrix for the specific patch/bundle ID for your version. Until patching is complete, reduce exposure by restricting network access to the WebCenter Sites HTTP endpoints so they are not reachable from the internet or untrusted networks (place behind a VPN or IP allowlist), and front the application with a WAF to inspect and filter anomalous HTTP requests; the trade-off is that overly aggressive filtering or access restriction can break legitimate content-author and delivery traffic, and neither control fully substitutes for the vendor patch given the unauthenticated network vector.
