CVE-2026-35308Network attack vector

Unauthenticated takeover via undisclosed HTTP flaw

Published Jun 16, 2026 · Updated Jun 16, 2026

Improper access control in Oracle Coherence allows remote attackers to take over affected releases through unauthenticated HTTP requests. Oracle identifies the affected locus only as Centralized Third Party Jars and has not published the specific jar, request handler, or improper operation. Network access to the HTTP service is sufficient, with no credentials or user interaction required, and compromise crosses the Coherence security scope to affect confidentiality, integrity, and availability.
