CVE-2026-10101
Assisted-service: assisted-service: infraenv status leaks referenced pull-secret contents to namespace view users
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`.

Action Type Old Value New Value Added Translation Title: Multicluster Engine for Kubernetes de Red Hat, Description: El servicio asistido por ACM/MCE escribe los contenidos brutos del pull-secret referenciado en InfraEnv.status.conditions[].message cuando falla la validación del pull-secret. Un principal de espacio de nombres con el ClusterRole view predeterminado no puede leer directamente Secrets, pero puede leer objetos InfraEnv y recuperar los datos .dockerconfigjson del Secret referenciado desde el estado. Esto elude la separación RBAC de Kubernetes/OpenShift entre los visores de espacio de nombres de solo lectura y los lectores de Secrets. En la prueba reproducida, a la misma ServiceAccount se le denegó get y list en Secrets, pero recuperó los campos sintéticos del pull-secret username, password, email y auth en base64 a través de InfraEnv.status. -
