What is CVE-2026-18950?
CVE-2026-18950 is a high-severity vulnerability in Red Hat OpenShift AI (RHOAI), published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A flaw was found in odh-dashboard. An authenticated user of the dashboard can exploit a vulnerability related to how RoleBindings are created. The system does not properly validate the `roleRef` field, allowing a user to specify an arbitrary role, including highly privileged ones like `cluster-admin`. This can lead to privilege escalation, where an attacker gains unauthorized elevated access within their namespace and potentially persistent control over the system.
