Authenticated takeover via undisclosed Open Integration flaw

Published Aug 18, 2026 · Updated Aug 20, 2026

Access-control failure in Oracle Siebel CRM Integration 25.12 through 26.6 allows remote authenticated users to take over the product via HTTP. Oracle identifies Open Integration as the component but has not disclosed the affected locus or the wrong operation performed on request data. A low-privileged account is required, and successful exploitation compromises the integration service with potential impact beyond its security scope.
