Description OSIDB Bzimport 2026-06-04 11:55:46 UTC
A flaw was found in the Cloud Credential Operator (CCO) Mint-mode CredentialsRequest manifests shipped with OpenShift Container Platform for AWS. The CredentialsRequest specifications for the Image Registry, Machine API, Ingress Operator, and EBS CSI Driver request IAM policies with Resource: "*" for destructive actions (S3 CreateBucket/DeleteBucket/PutObject/DeleteObject, EC2 TerminateInstances/RunInstances, Route53 ChangeResourceRecordSets, EC2 DeleteVolume/DeleteSnapshot). This grants the provisioned operator IAM credentials access to any AWS resource in the account, not just resources owned by the cluster. An attacker who obtains these credentials (via pod compromise, RBAC escalation, or Secret read) can perform destructive operations against unrelated AWS resources in the same account, including deleting S3 buckets, terminating EC2 instances, modifying DNS records in unrelated hosted zones, and deleting EBS volumes belonging to other workloads or clusters.
