CVE-2026-101455: Medium severity Oracle Siebel CRM Development vulnerability

Q: Who is exposed to this vulnerability?

Oracle Siebel CRM Development deployments using affected supported versions 17.0 through 26.9 are exposed, but exploitation requires an attacker to have a low-privileged account and logon access to the infrastructure where the product runs.

Q: What level of access does an attacker need to exploit it?

The attacker must be able to log on to the Siebel CRM Development execution infrastructure with low privileges. The vulnerability is local and has high attack complexity; no user interaction is required.

Q: What could a successful attacker do?

A successful attack can provide unauthorized access to critical data or all data accessible to Siebel CRM Development, and can allow creation, deletion, or modification of that data.

Q: How can I determine whether my environment is affected?

Verify whether Oracle Siebel CRM Development is deployed and whether its supported version falls from 17.0 through 26.9. Also identify accounts with logon access to the infrastructure hosting the product, since that access is required for exploitation.
