17 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Parsing logic was vulnerable to accepting kubeadm-style bootstrap tokens during standard credential extraction, allowing unauthorized client access. Secure parsing must validate token types strictly.
Denial of Service: Uninitialized core runtime structures were accessed without validation in the secrets-encrypt handlers, leading to nil pointer dereference panics on unready servers.
Privilege Escalation: Sharing highly-privileged cluster-admin credentials across distinct cluster components allowed lateral privilege escalation. Separation of concerns using dedicated RBAC roles is vital.
