DescriptionCVE.org

Vulnerability in the Oracle WebCenter Content product of Oracle Fusion Middleware (component: Content Server). The supported version that is affected is 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Content. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Content, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle WebCenter Content accessible data as well as unauthorized access to critical data or complete access to all Oracle WebCenter Content accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N).

AnalysisAI

Cross-product compromise of Oracle WebCenter Content 14.1.2.0.0 (Fusion Middleware Content Server) allows a remote unauthenticated attacker to abuse a victim's browser session to gain high-impact read and write access to all WebCenter Content data, with scope change extending the impact to additional Oracle products. The CVSS 3.1 base score is 9.3 with a scope-changed vector requiring user interaction (UI:R), and no public exploit identified at time of analysis.

Technical ContextAI

Oracle WebCenter Content is the enterprise content management server component of Oracle Fusion Middleware 14c (14.1.2.0.0), responsible for document, records, and digital asset management across integrated Oracle stacks. The CPE 'cpe:2.3:a:oracle_corporation:oracle_webcenter_content' confirms the Content Server subcomponent is the vulnerable surface. CWE is unassigned by Oracle (typical for CPU advisories), but the vector (AV:N/AC:L/PR:N/UI:R/S:C with C:H/I:H/A:N) combined with the 'Authentication Bypass' tag is most consistent with a client-side / HTTP-borne flaw - likely reflected XSS, CSRF, or a request-forgery-style weakness in the Content Server web UI - where a victim's authenticated browser context is leveraged to perform privileged actions and reach adjacent Oracle components.

RemediationAI

Apply Oracle's June 2026 Critical Patch Update for Fusion Middleware as documented at https://www.oracle.com/security-alerts/cspujun2026.html; an exact patched build string is not enumerated in the provided data, so treat this as 'Patch available per vendor advisory' and pull the precise patch number from My Oracle Support for WebCenter Content 14.1.2.0.0. Until the CPU is deployed, restrict Content Server's HTTP/HTTPS endpoints to trusted networks or VPN, place a WAF in front of the UI to filter suspicious links and cross-origin requests, enforce strict same-site and CSRF tokens at the reverse-proxy layer, and warn privileged Content Server users (administrators, contributors) against clicking unsolicited links to the application - recognising that proxy-level filtering may break some legitimate WebCenter integrations and that browser-vector mitigations only reduce, not eliminate, the UI:R exploitation path.
