CVE-2026-62590Network attack vector

Authenticated service takeover

Published Aug 18, 2026 · Updated Aug 20, 2026

Open Integration in Oracle Siebel CRM Integration 25.12 through 26.6 allows remote authenticated users to take over the service via HTTP. Oracle has not published the affected function or the incorrect operation performed on attacker-controlled input. Exploitation requires low-privilege credentials and high attack complexity; successful compromise grants full control of the integration and can affect connected products beyond the component boundary.
