CVE-2026-62539Network attack vector

Unauthenticated server takeover

Published Aug 18, 2026 · Updated Aug 25, 2026

Oracle Hyperion Infrastructure Technology 11.2.25.0.000 allows remote attackers to take over the server through unauthenticated HTTP requests. Oracle identifies the affected component as Installation and Configuration but has not disclosed the flawed request handler or operation on untrusted input. Network reachability to the HTTP service is sufficient; successful exploitation compromises application confidentiality, integrity, and availability.
