Vulnerability Title
Models-as-a-service: red hat openshift ai: maas-api and maas-controller serviceaccounts with excessive permissions lead to privilege escalation
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the maas-api and maas-controller ServiceAccounts within Red Hat OpenShift AI. These ServiceAccounts are granted cluster-wide permissions that exceed their operational requirements. An attacker who compromises the identity of these ServiceAccounts, either through a remote code execution vulnerability or by creating a malicious pod in the same namespace, could exploit these excessive permissions. This could lead to full cluster administrator privileges through the creation of new ClusterRoleBindings or the disclosure of sensitive information by accessing all secrets across the cluster.
