Vulnerability from github – Published: 2026-05-29 18:31 – Updated: 2026-05-29 18:31

Details

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.

Severity

6.3 (Medium)

CVE-2026-10101 (GCVE-0-2026-10101)

Vulnerability from cvelistv5 – Published: 2026-05-29 15:23 – Updated: 2026-05-29 19:31

Title

Assisted-service: assisted-service: infraenv status leaks referenced pull-secret contents to namespace view users

Summary

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`.
