A flaw was found in the AAP Controller's HashiCorp Vault credential plugin. The kubernetes_auth() function in awx_plugins/credentials/hashivault.py reads the controller pod's Kubernetes service account token and sends it to an attacker-controlled URL when a HashiCorp Vault Secret Lookup credential with kubernetes_role authentication is tested. An authenticated attacker with credential-creation privileges can exfiltrate the service account token, gaining Kubernetes API access to the control plane namespaces with full pod CRUD and secret read permissions, including database credentials and the Django SECRET_KEY.
