Technical details

This vulnerability exists in the Core component of Oracle Coherence (Oracle Fusion Middleware). It is classified as easily exploitable and requires the attacker to have access to the physical communication segment (adjacent network) attached to the hardware where Oracle Coherence is executing. No authentication or user interaction is required for exploitation. A successful attack results in a complete compromise of the Oracle Coherence instance, impacting confidentiality, integrity, and availability. The vulnerability is addressed in the Oracle Critical Patch Update for July 2026.
