Description
ACM/MCE assisted-service writes raw referenced pull-secret contents into `InfraEnv.status.conditions[].message` when pull-secret validation fails. A namespace principal with the stock `view` ClusterRole cannot directly read Secrets, but can read `InfraEnv` objects and recover the referenced Secret's `.dockerconfigjson` data from status.
This bypasses the Kubernetes/OpenShift RBAC separation between read-only namespace viewers and Secret readers. In the reproduced proof, the same ServiceAccount was denied `get` and `list` on Secrets, but recovered synthetic pull-secret `username`, `password`, `email`, and base64 `auth` fields through `InfraEnv.status`.
