2DescriptionCVE.org
Vulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Runtime Tools). 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 Portal. Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Portal. 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 takeover of Oracle WebCenter Portal is achievable by an unauthenticated remote attacker via HTTP, affecting the Runtime Tools component in versions 12.2.1.4.0 and 14.1.2.0.0 of the Fusion Middleware stack. The CVSS vector rates this 8.1 due to high attack complexity (AC:H), meaning exploitation requires specific but unspecified preconditions to be met - yet successful exploitation yields complete compromise of confidentiality, integrity, and availability. …

Vulnerability AssessmentAI
| Exploitation | Network access via HTTP is required, consistent with AV:N. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.1 score reflects a high-impact vulnerability tempered by AC:H, which materially reduces the exploitability compared to an AC:L equivalent (which would score 9.8). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle Critical Security Patch Update (CPU) for August 2026, which addresses this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Oracle WebCenter Portal deployments running versions 12.2.1.4.0 or 14.1.2.0.0 in production and stage environments; immediately restrict network access to these systems via firewall rules limiting connectivity to trusted administrative networks only. …
