Title
Cloud-credential-operator: cco mint-mode credentialsrequest manifests grant account-wide iam access beyond cluster scope on aws
Summary
A flaw was found in the OpenShift Cloud Credential Operator Mint-mode IAM policies for AWS. Operator credentials are provisioned with account-wide scope for destructive actions rather than being restricted to cluster-owned resources, enabling cross-scope impact after credential compromise.
