CVE-2026-18950
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.
Statement
Critical: An improper authorization flaw in Red Hat OpenShift AI's odh-dashboard component allows an authenticated user to escalate privileges. By crafting a RoleBinding with an arbitrary roleRef, an attacker can grant themselves any ClusterRole, including 'cluster-admin', within their namespace. This vulnerability requires an authenticated dashboard user and an enabled dashboard component in RHOAI/ODH.
Mitigation
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
