CVE-2026-62512Network attack vector

Low-privileged management-plane takeover

Published Aug 18, 2026 · Updated Aug 21, 2026

Undisclosed flaw in Siebel Cloud Manager in Oracle Siebel CRM Cloud Applications 22.3 through 26.6 allows attackers to take over it via HTTP. Oracle has not disclosed the failing endpoint, authorization check, or state-changing operation in Siebel Cloud Manager, so the specific takeover path remains undisclosed in public source records. Reachability requires network access over HTTP and valid low-privilege access to the application; successful exploitation yields full compromise of the management plane and, per Oracle's scope-change assessment, can affect additional connected products.
