Executive brief
Oracle Coherence, a distributed data grid solution used for high-speed data processing and application scaling, contains a critical security vulnerability in its core component. An unauthenticated attacker can exploit this flaw over the network to gain full control of the system. This could lead to the complete exposure of sensitive cached data, unauthorized modification of information, and significant disruption to business operations.
Technical details
A critical vulnerability exists in the Core component of Oracle Coherence (versions 12.2.1.4.0 and 14.1.1.0.0). The flaw is easily exploitable by an unauthenticated attacker with network access via HTTP. Successful exploitation allows for a complete takeover of the Oracle Coherence instance, impacting confidentiality, integrity, and availability. While the specific vulnerability class (e.g., deserialization or injection) is not explicitly named in the advisory, the CVSS score of 9.8 and the 'takeover' description suggest a remote code execution or high-privilege bypass capability. Users are advised to refer to the Oracle Critical Patch Update for July 2026 for remediation steps.
