Alert meAnalysisAIv1 – Sep 15, 2026
Oracle Siebel CRM Deployment (Server Infrastructure component) versions 17.0 through 26.7 can be fully taken over by a low-privileged attacker who already holds a valid account and can reach the deployment over HTTP. The flaw is rated 7.5 with High complexity (AC:H), meaning it is not a trivial drive-by exploit but requires a favorable, harder-to-arrange condition to succeed; when it does, confidentiality, integrity, and availability are all fully compromised. There is no CISA KEV listing and no public exploit code identified at time of analysis, but Oracle has published a Security Alert with a patch, so exposure is patch-gated rather than just theoretical.
