A flaw was found in the managedcluster-import-controller. The Certificate Signing Request CSR auto-approval logic improperly validates incoming CSRs, specifically by not inspecting the signer name or decoding the PEM-encoded x509 CSR. This vulnerability allows a privileged service account on a...

CVE-2026-66795

The managedcluster-import-controller's CSR auto-approver skips validation of signer name, certificate subject, and requester identity, letting a privileged spoke-cluster service account submit a malicious CSR and escalate to hub-cluster admin. CVSS 9.1 critical; no exploitation evidence provided....

EUVD-2026-57686

A flaw was found in acm-search-v2-rhel9. An attacker with administrative privileges on the hub cluster, specifically with patch access to the Search Custom Resource CR, could exploit a vulnerability in the Collector.ImageOverride field. This allows the attacker to deploy an arbitrary container...

CVE-2026-71846

A flaw was found in insights-client. The component's ServiceAccount is bound to a ClusterRole granting cluster-wide secrets get, list, and watch permissions, while the code only requires access to a single specific Secret. This excessive privilege means that a compromise of the insights-client po...
