CVE-2026-101436: Medium severity Oracle Siebel CRM Cloud Applications vulnerability

Q: Who is realistically exposed to this vulnerability?

Exposure is limited to supported Oracle Siebel CRM Cloud Applications versions 22.3 through 26.9 that use the Siebel Cloud Manager component. An attacker must already have a high-privileged account and logon access to the infrastructure where the application runs.

Q: What could a successful attacker access?

Successful exploitation can result in unauthorized access to critical data or complete access to all data accessible through the affected Siebel CRM Cloud Applications deployment. The stated impact is confidentiality only; integrity and availability impacts are not identified.

Q: Does this appear exploitable remotely or by an unauthenticated attacker?

No. The CVSS vector identifies local attack access, high attack complexity, and high privileges required, with no user interaction required.
