CVE-2026-83412
HighCVSS 8.1Summary
Vulnerability in Oracle Coherence (Oracle Fusion Middleware), component Core, affecting versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. A low-privileged authenticated attacker with TCP network access can access data and create, delete, or modify data. CVSS 3.1 Base Score 8.1.
Risk Assessment
A low-privileged attacker can compromise the confidentiality and integrity of critical data in Oracle Coherence. This may lead to data leakage and unauthorized modifications in the cluster.
Recommendation
Urgently apply the Oracle Critical Patch Update for Oracle Fusion Middleware and restrict network access to Oracle Coherence. Also monitor TCP traffic and review low-privileged accounts.
