CVE-2026-61330Network attack vector

Low-privileged application takeover

Published Aug 18, 2026 · Updated Aug 21, 2026

Privilege escalation in Oracle Siebel CRM Cloud Applications 22.3 through 26.6 allows remote authenticated users to take over application via HTTP. Oracle describes the flaw only as a Siebel Cloud Manager issue; no public advisory, CVE record, or reviewed enrichment discloses the vulnerable function or the incorrect handling of untrusted input or authorization state. Reachability requires low-privileged network access and no user interaction, so exposure is limited to deployments that expose Siebel Cloud Manager to authenticated users, but successful exploitation fully compromises the affected instance.
