Summary
Vulnerability in Oracle JDeveloper (Resource Catalog Services component) affecting versions 12.2.1.4.0 and 14.1.2.0.0. An unauthenticated attacker with network access via HTTP can gain unauthorized access to critical data and cause a partial denial of service. CVSS 3.1 Base Score 8.2.
Risk Assessment
Possible leakage of critical data and partial disruption of service availability, which may affect business continuity. Ease of exploitation without authentication increases the risk.
