Description

A flaw was found in AWX. The container group pod_spec_override field uses an incomplete blocklist that only restricts automountServiceAccountToken, allowing injection of initContainers, serviceAccountName overrides, and projected service account token volumes. An AAP platform administrator can exploit this to escalate privileges to OpenShift namespace-level access and exfiltrate namespace secrets.
