Lifecycle Timeline
1DescriptionCVE.org
Vulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Composer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebCenter Portal. While the vulnerability is in Oracle WebCenter Portal, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Portal. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
AnalysisAI
Privilege escalation and full takeover of Oracle WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0 is achievable by a low-privileged remote attacker through the Composer component, with a scope change that lets the impact reach additional products in the Fusion Middleware stack. Oracle rates the flaw 9.9 CVSS due to the combination of low attack complexity, low privilege requirement, and full CIA impact, and no public exploit has been identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold valid credentials for any low-privileged role on Oracle WebCenter Portal 12.2.1.4.0 or 14.1.2.0.0 (CVSS PR:L) and be able to reach the Composer component over HTTP/HTTPS; no user interaction by another victim is required (UI:N) and attack complexity is low (AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high priority issue rather than an inflated CVSS number: the vector AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H means any authenticated portal user, even a low-privileged content contributor, can pivot over the network with low complexity to take over the portal and impact adjacent Fusion Middleware components via the scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker phishes or compromises a low-privileged WebCenter Portal account - for example a content contributor - then sends crafted HTTP requests to the Composer component to inject a malicious task-flow or resource definition that is processed server-side. Because the flaw causes a scope change, the resulting code or data manipulation reaches beyond the portal into the underlying Fusion Middleware stack, giving the attacker takeover of the portal and a foothold to pivot into integrated WebLogic-hosted applications. … |
| Remediation | Apply the Oracle Critical Patch Update for June 2026 to both the 12.2.1.4.0 and 14.1.2.0.0 branches as published at https://www.oracle.com/security-alerts/cspujun2026.html - this is the only vendor-released fix and Oracle policy is that interim patches are not provided. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Identify all systems running WebCenter Portal 12.2.1.4.0 or 14.1.2.0.0; immediately restrict logical and network access to the Composer component to administrative staff only; disable remote access where operationally feasible. …
