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 low privileged attacker with network access via HTTP to compromise Oracle WebCenter Portal. 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 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).
AnalysisAI
Oracle WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0 contain a flaw in the Runtime Tools component that lets a low-privileged, network-positioned attacker read and partially modify portal data via HTTP. Oracle rates it 7.1 (AV:N/AC:L/PR:L/UI:N, C:H/I:L), meaning exploitation is trivial once any valid low-privileged account is held, with full confidentiality impact against the portal's accessible data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Mandatory prerequisite: a valid, authenticated Oracle WebCenter Portal session with at least low privileges (CVSS PR:L) - the attack does not work against anonymous users. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N) describes a low-skill, low-complexity attack requiring only a valid low-privileged account and no user interaction - an important nuance, since the PR:L metric means this is not an unauthenticated pre-auth bug and therefore cannot be mass-exploited by internet-wide scanning alone. … 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 fix from Oracle's Critical Security Patch Update advisory (https://www.oracle.com/security-alerts/cspusep2026.html), which covers WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0 - Oracle typically ships these fixes as bundled Patch Set Updates or interim patches on My Oracle Support rather than standalone downloads, so verify the exact patch number and prerequisite OPatch level before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
