Vulnerability in the Oracle JDeveloper product of Oracle Fusion Middleware (component: Resource Catalog Services). 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 JDeveloper. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle JDeveloper accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle JDeveloper. CVSS 3.1 Base Score 8.2 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L).
AnalysisAI

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the Oracle JDeveloper instance's Resource Catalog Services component is deployed and reachable over HTTP from the attacker's network position; the CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms that no credentials, no user interaction, and no special conditions beyond HTTP reachability are required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector is the strongest signal here: AV:N/AC:L/PR:N/UI:N means no authentication, no user interaction, and no special complexity, so the only real barrier is network reachability of the Resource Catalog Services HTTP endpoint. … 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 fix is to apply the Oracle Critical Patch Update release published at https://www.oracle.com/security-alerts/cspusep2026.html - this advisory is the authoritative source for the patched build numbers for JDeveloper 12.2.1.4.0 and 14.1.2.0.0, which were not enumerated in the provided data, so verify the exact CPU build against your installed version before declaring remediation complete. … Detailed patch versions, workarounds, and compensating controls in full report. |
