Information disclosure in Oracle Coherence 15.1.1.0.0 lets a low-privileged attacker with HTTP network access read critical data or the entire contents of Coherence-accessible caches, and because the CVSS vector reports a scope change, products built on top of that grid can be exposed as well. Oracle scores it 6.3 with high attack complexity, so it is not a trivial drive-by exploit; the feed contains no public exploit code and no CISA KEV entry, and the only remediation reference is Oracle's Critical Security Patch Update advisory. …
