## Technical details

The vulnerability is an integrity bypass in the Core component of Oracle Coherence that requires high privileges and local logon access to the infrastructure where Coherence executes. The attack has high complexity and does not involve network access or user interaction. A successful exploit allows an attacker to perform unauthorized data manipulation operations (update, insert, delete) on Coherence-managed data. No integrity (C), availability (A), or confidentiality (I) impacts beyond integrity modification are present. The vulnerability affects versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0; patch availability is not confirmed in available sources.
