Summary

A flaw was found in the Open Cluster Management (OCM) when a user have access to the worker nodes which has the cluster-manager-registration-controller or cluster-manager deployments. A malicious user can take advantage of this and bind the cluster-admin to any service account or using the service account to list all secrets for all kubernetes namespaces, leading into a cluster-level privilege escalation.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
