CVE-2026-61318Network attack vector

Unauthenticated application takeover

Published Aug 18, 2026 · Updated Aug 20, 2026

Unspecified vulnerability in Siebel Cloud Manager in Oracle Siebel CRM Cloud Applications 22.3 through 26.6 allows remote attackers to take over the application via HTTP. Oracle's public records do not disclose the vulnerable endpoint, function, or input handling error, and the reviewed CNA, NVD, and Oracle advisory material only state that unauthenticated HTTP requests can compromise the deployment. Exposure is limited to environments where Siebel Cloud Manager is network reachable; Oracle rates the resulting impact as complete compromise of confidentiality, integrity, and availability.
