CVE-2026-107176 — Cluster-samples-operator: role reads all secrets in openshift-config, not just pull-secret
A flaw was found in the cluster-samples-operator. The RBAC Role coreos-pull-secret-reader in namespace openshift-config grants get, list, and watch permissions on all Secret resources without resourceNames scoping. The operator only requires access to the pull-secret Secret. If the samples-operator pod or its service account token is compromised through a separate vulnerability, an attacker could read all secrets in openshift-config, potentially including OAuth identity provider credentials, cloud provider credentials, and other sensitive cluster configuration.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+1
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat OpenShift Container Platform 4).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (privilege escalation), errors and authentication anomalies.

What should defenders know first?
CVE-2026-107176 is "Cluster-samples-operator: role reads all secrets in openshift-config, not just pull-secret", rated Medium. It affects Red Hat OpenShift Container Platform 4 (Red Hat); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.8 describes technical severity. EPSS 0.16% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
