CVE-2023-22648Network attack vector

Persistent access via stale Azure AD permissions

Published Jun 1, 2023 · Updated Oct 9, 2024

Improper authorization in Rancher 2.6.7 through 2.6.12 and 2.7.0 through 2.7.3 allows remote authenticated users to retain access via active sessions. Rancher persists Azure AD-derived permissions in active UI, kubeconfig, and API-key sessions and does not refresh them after group downgrades or removal. Azure AD integration and an existing affected session are required; retained permissions survive pod restarts until the user logs out and authenticates again.
