Executive brief
Oracle Coherence, a data grid solution used for high-speed data processing and storage, contains a critical security flaw in its core component. An unauthorized person can remotely take full control of the system over the network without needing any login credentials. This could lead to a total loss of data confidentiality, unauthorized modification of information, and a complete shutdown of the service.
Technical details
A critical vulnerability exists in the Core component of Oracle Coherence (versions 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0). The flaw is easily exploitable by an unauthenticated attacker with network access via TCP. While the specific vulnerability class (e.g., deserialization or protocol flaw) is not explicitly named in the advisory, the impact is a complete compromise of Confidentiality, Integrity, and Availability (CVSS 9.8). Attackers can achieve full system takeover without user interaction. Users are advised to refer to the Oracle Critical Patch Update (CPU) for July 2026 for remediation steps.
