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. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Portal. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Portal, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Portal accessible data as well as unauthorized update, insert or delete access to some of Oracle WebCenter Portal accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).
AnalysisAI
Unauthenticated remote exploitation of Oracle WebCenter Portal's Runtime Tools component (versions 12.2.1.4.0 and 14.1.2.0.0) enables a network-based authentication bypass over HTTP, contingent on a single human-interaction step by a target user. Successful exploitation yields complete confidentiality exposure of all data accessible to the portal instance and limited unauthorized write capability, with scope-change implications that can cascade into co-hosted Oracle Fusion Middleware products. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target system is running Oracle WebCenter Portal version 12.2.1.4.0 or 14.1.2.0.0 with the Runtime Tools component accessible via HTTP over a network reachable by the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 8.2 (High) reflects a network-accessible, low-complexity, unauthenticated attack requiring only a single user-interaction step - a profile consistent with reflected injection or cross-site request forgery patterns that weaponize an authenticated user's session. … 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 | The primary remediation is to apply the patches included in Oracle's August 2026 Critical Patch Update, available through the Oracle Support portal referenced at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all systems running affected WebCenter Portal versions (12.2.1.4.0 and 14.1.2.0.0), enable detailed access logging on the Runtime Tools component, and review logs for exploitation attempts. …
