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.

Vulnerability AssessmentAI

Exploitation Requires (1) a reachable Oracle WebCenter Content 14.1.2.0.0 Content Server instance over HTTP/HTTPS, and (2) human interaction from a different user than the attacker (UI:R) - typically a currently authenticated WebCenter Content user, most impactfully an administrator or contributor, who must follow an attacker-supplied link or load attacker content in their browser. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals are mixed but lean toward high real-world risk: CVSS 3.1 is 9.3 with AV:N/AC:L/PR:N and a scope change (S:C) reflecting cross-product blast radius, which Oracle itself rated 'easily exploitable.' UI:R is the principal limiter - a logged-in user (likely a content author/administrator with active session) must be lured into clicking or visiting attacker content, which moves this away from worm-style mass exploitation toward phishing or watering-hole abuse against privileged operators. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker emails a Content Server administrator a link to an attacker-controlled page; when the admin (already logged into WebCenter Content) visits it, the page issues a crafted HTTP request to the Content Server, which carries the victim's session and performs unauthorized reads or modifications of managed content and, due to scope change, of data in an integrated Oracle product. No public exploit is identified at time of analysis, but Oracle's own 'easily exploitable' rating suggests reliable weaponization is plausible once the advisory details are reverse-engineered.
Remediation 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. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all Oracle WebCenter Content 14.1.2.0.0 instances; restrict network access to administrative consoles to trusted networks; enable comprehensive audit logging of all content access and modifications. …
