Low-privileged access and modification of cached data
Published Sep 15, 2026 · Updated Sep 15, 2026
Access control flaw in Oracle Coherence 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 allows remote authenticated users to read and alter data. Oracle identifies the Core component and TCP exposure but has not published the affected request path, authorization check, or other code-level mechanism. Network access and low-privileged credentials are required; successful exploitation permits creation, deletion, modification, or complete disclosure of Coherence-accessible data without affecting availability.
