December 2024 — Radius: Implemented RBAC least-privilege hardening for UCP by tightening rbac.yaml and removing unused permissions (commit 338369290443cbd398cb9e77bbd24603faec2a08; 'Changing permissions of UCP - removing unused permissions (#8080)'). This reduces the service account's privilege surface, enhancing security while preserving functionality. No major bugs fixed this month; the focus was on secure, maintainable access controls with clear auditability. Impact: lower risk of privilege escalation, improved compliance readiness, and a cleaner RBAC policy for future changes.
