    High [CVE-2026-18950] Confused-deputy privilege escalation via unchecked roleRef in RoleBinding creation

    CVE-2026-18950Source published Source updated

    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. By crafting a RoleBinding with an arbitrary roleRef, an attacker can grant themselves any ClusterRole, including 'cluster-admin', within their namespace. Red Hat severity: Critical — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-266. Affected Red Hat products: Red Hat OpenShift AI 2.25; Red Hat…

    Mitigation guidance
    • To mitigate this issue, restrict access to the OpenShift AI dashboard to only trusted users. Additionally, implement an Open Policy Agent (OPA) or Gatekeeper policy to prevent the creation of RoleBindings that reference privileged ClusterRoles like cluster-admin within user namespaces. Regularly monitor audit logs for any unauthorized RoleBinding creations.
