Authenticated disclosure of critical cache data
Published Sep 15, 2026 · Updated Sep 15, 2026
Information disclosure in Oracle Coherence 15.1.1.0.0 Core allows remote authenticated users to read critical cache data via HTTP. Oracle has not published the vulnerable Core operation or explained how crafted HTTP input bypasses its intended data-access boundary. Exploitation requires low-privileged access and difficult conditions, but it exposes all data accessible to the compromised Coherence context.
