Executive brief
Oracle Coherence, a distributed data grid solution used for high-speed data processing and application scaling, contains a critical security vulnerability. An unauthenticated attacker can exploit this flaw over a network to gain full control of the affected system. This could lead to the theft of sensitive data, disruption of business operations, and total compromise of the application environment.
Technical details
A critical vulnerability exists in the Core component of Oracle Coherence (Oracle Fusion Middleware). The flaw is easily exploitable by an unauthenticated attacker with network access via TCP. While the specific vulnerability class (e.g., deserialization or remote code execution) is not explicitly named in the advisory, the CVSS score of 9.8 and the 'takeover' impact indicate a severe flaw allowing for complete loss of confidentiality, integrity, and availability. Affected versions include 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. Users should refer to the Oracle Critical Patch Update (CPU) for July 2026 for remediation guidance.
