## Technical details

A critical vulnerability exists in the Core component of Oracle Coherence (versions 12.2.1.4.0, 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. Successful exploitation allows for a complete takeover of the Oracle Coherence instance, impacting confidentiality, integrity, and availability (CVSS 9.8). While specific CWE details were not provided in the advisory, the high impact and lack of authentication suggest a serious flaw in the handling of network-based requests or serialization within the core cluster communication protocols. Users are advised to refer to the Oracle Critical Patch Update for July 2026 for remediation steps.
