CVE-2026-107176 Red Hat CVE debrief

A flaw in the cluster-samples-operator allows unauthorized access to all secrets in the openshift-config namespace if the samples-operator pod or its service account token is compromised. This issue arises from the RBAC Role coreos-pull-secret-reader granting excessive permissions on all Secret resources without proper scoping. The vulnerability could lead to exposure of sensitive cluster configuration, including OAuth identity provider credentials and cloud provider credentials. Defenders should prioritize verifying the integrity of the samples-operator pod and its service account, assessing exposure to potential compromise, and ensuring that only necessary permissions are granted

Who should care

Defenders responsible for securing the openshift-config namespace and cluster configuration should assess exposure to potential compromise and prioritize verifying the integrity of the samples-operator pod and its service account.

Why it matters

CVE-2026-107176 allows unauthorized access to all secrets in the openshift-config namespace if the samples-operator pod or its service account token is compromised. Defenders should prioritize verifying the integrity of the samples-operator pod and its service account, assessing exposure to potential compromise, and ensuring that only necessary permissions are granted to the operator.

  • Potential unauthorized access to sensitive cluster configuration
  • Possible exposure of OAuth identity provider credentials
  • Potential exposure of cloud provider credentials
  • Compromise of samples-operator pod or service account token could lead to further exploitation

Technical summary

The cluster-samples-operator has a flaw in its RBAC Role coreos-pull-secret-reader, which grants get, list, and watch permissions on all Secret resources in the openshift-config namespace without proper resourceNames scoping. This allows unauthorized access to all secrets in the namespace if the samples-operator pod or its service account token is compromised. The vulnerability could lead to exposure of sensitive cluster configuration, including OAuth identity provider credentials and cloud provider credentials. Defenders should prioritize verifying the integrity of the samples-operator pod and its service account, assessing exposure to potential compromise, and ensuring that only necessary permissions are

Defensive priority

Defenders should prioritize verifying the integrity of the samples-operator pod and its service account, assessing exposure to potential compromise, and ensuring that only necessary permissions are granted to the operator.

Recommended defensive actions

  • Verify the integrity of the samples-operator pod and its service account
  • Assess exposure to potential compromise
  • Ensure that only necessary permissions are granted to the operator
  • Review and restrict access to sensitive cluster configuration
  • Monitor relevant logs for exposed assets that need extra review
  • Track exceptions and retest remediated assets
  • Review compensating controls for exposed systems while remediation is scheduled and verified
