CVE-2026-46920Network attack vector

Unauthenticated application takeover

Published Jun 16, 2026 · Updated Jun 16, 2026

Missing authentication in Oracle Siebel CRM Cloud Applications 17.0 through 26.5 allows remote attackers to take over the application via HTTP. Oracle identifies Siebel Cloud Manager as the affected component but has not published the vulnerable locus or the incorrect operation performed on HTTP input. Exploitation requires no credentials or user interaction, although Oracle rates the attack complexity as high; successful exploitation grants control of the application.
