Summary
Why
The deployment RPC helpers disabled TLS verification for every URL, including production HTTPS hostnames. This allowed an on-path attacker to spoof bootstrap, checkpoint, or staking responses. The URL normalizer also silently fell back from HTTPS to HTTP when a bare host probe failed.
Bare IP inputs retain the existing explicit HTTP behavior; secure deployments should use an
https://URL.Validation
