CVE-2026-60309

Unauthenticated adjacent-network cluster takeover

Published Jul 21, 2026 · Updated Jul 21, 2026

Access control failure in Coherence Core 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 allows remote attackers to take over clusters. Oracle has not disclosed the Core operation or failed access-control check involved in processing unauthenticated TCP traffic. Exploitation requires access to the physical communication segment attached to the host, and takeover compromises cluster confidentiality, integrity, and availability.
