AI Analysis
Technical Summary
This vulnerability in Oracle Coherence, a component of Oracle Fusion Middleware, allows a high privileged attacker who already has logon access to the infrastructure hosting Oracle Coherence to perform unauthorized update, insert, or delete operations on some data accessible by Oracle Coherence. 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. The CVSS 3.1 vector (AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N) reflects that the attack requires local access with high privileges and high attack complexity, with no impact on confidentiality or availability but limited impact on integrity. Oracle's September 2026 Critical Security Patch Update includes fixes for this vulnerability among 673 patches across multiple products. Oracle strongly recommends applying these patches without delay to mitigate the risk.
Potential Impact
The impact is limited to unauthorized modification of some data within Oracle Coherence by a high privileged attacker with local access. There is no impact on confidentiality or availability. The low CVSS score (1.9) reflects the difficulty of exploitation and limited scope of impact.
Mitigation Recommendations
Oracle has released a Critical Security Patch Update in September 2026 that addresses this vulnerability. Customers should apply the relevant patches for Oracle Coherence versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 promptly. Oracle strongly recommends remaining on actively-supported versions and applying security patches without delay to prevent exploitation. No additional mitigations are specified beyond patching.
