A fix is available — apply it.

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.
