The tekton-scheduler-rolebinding ClusterRoleBinding grants the system:authenticated group write access to Kueue and cert-manager custom resources via the tekton-scheduler-role ClusterRole. When Kueue or cert-manager CRDs are present on the cluster, any authenticated user can disrupt workload scheduling, tamper with scheduling priorities, delete other tenants' Workload objects, or induce cert-manager to overwrite TLS Secrets including the default ingress controller certificate.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
