CVE-2026-83415Network attack vector

Authenticated takeover via undisclosed Core flaw

Published Sep 15, 2026 · Updated Sep 15, 2026

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 take over the service via HTTP. Oracle has not published the affected request, handler, or incorrect operation in the Core component. Exploitation requires low-privileged credentials, network access to an HTTP endpoint, and high-complexity conditions; success grants full control of Coherence data and service behavior.
