Remove the DNS over HTTPS (DoH) proxy feature built on CoreDNS due to security vulnerabilities (GO-2025-3942, GO-2026-4289). This removes: - Standalone proxy-dns command (cloudflared proxy-dns) - Tunnel subcommand (cloudflared tunnel proxy-dns) - Proxy-dns flags for tunnel run (--proxy-dns, --proxy-dns-port, etc.) - Config file resolver section support - tunneldns/ package (CoreDNS-based implementation) - Related component tests BREAKING CHANGE: The proxy-dns feature is no longer available. Users should migrate to alternative DNS over HTTPS solutions. |
