AnalysisAI

Privileged takeover of Oracle WebCenter Content (Content Server component) affects supported versions 12.2.1.4.0 and 14.1.2.0.0, enabling a high-privileged attacker with HTTP network access to fully compromise the instance and pivot to additional Fusion Middleware products via a scope change. The CVSS 3.1 base score is 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), reflecting low attack complexity and full CIA impact. …

Vulnerability AssessmentAI

Exploitation Attacker must (1) hold a high-privileged Oracle WebCenter Content account (PR:H - administrator-equivalent role on the Content Server), (2) have HTTP/HTTPS network reachability to the Content Server instance, and (3) be targeting a supported version 12.2.1.4.0 or 14.1.2.0.0 prior to the June 2026 CPU. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H yields 9.1 because the scope change and full CIA impact outweigh the PR:H requirement - meaning a legitimate high-privileged Content Server account (an administrator or equivalent role) can compromise both WebCenter Content and adjacent products. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained a WebCenter Content administrator credential - through phishing, password reuse, or chaining from a separate Fusion Middleware vulnerability - authenticates to the Content Server over HTTP from anywhere on the network and invokes the vulnerable privileged function to take full control of WebCenter Content. Because the issue is scope-changing, the same action also lets them reach and tamper with adjacent products such as the underlying WebLogic domain or integrated repositories. …
Remediation Patch available per vendor advisory: apply the fixes for Oracle WebCenter Content shipped in the June 2026 Oracle Critical Patch Update (https://www.oracle.com/security-alerts/cspujun2026.html) to both the 12.2.1.4.0 and 14.1.2.0.0 branches, following Oracle's standard CPU prerequisites and the WebCenter Content patch readme. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

24 hours: Identify all Oracle WebCenter Content deployments running 12.2.1.4.0 or 14.1.2.0.0; restrict administrative access and review recent high-privilege account activity for compromise indicators. …
