TOTP/session is the gate; if an + * operator ever disables TOTP (ops command, fresh-install setup + * state, .disabled-* rename of totp-config.json), an unauthenticated + * attacker reaching `https://ca.sami/api/ca/cert/?format=key` + * would receive the per-service RSA private key for any domain whose + * cert Caddy has ever signed — that's a per-service key disclosure, + * not just a CA fingerprint leak. Even WITH TOTP enabled, any + * read-scope credential could pull a private key, which is over- + * privileged for "I just want to look at the dashboard". + * 2. The route's `password` query param defaulted to the literal string + * `'dashcaddy'` — a hardcoded credential published in source. Every + * PFX file Caddy signed silently used the same published password. + * 3. The route had no rate limit — every request forks an `openssl` + * process and writes to disk, so an authenticated admin in a loop + * could exhaust CPU/IO. + * + * Post-fix (this commit): + * 1. /api/v1/ca/cert/ + /api/v1/ca/certs removed from + * PUBLIC_ROUTES — TOTP/session always required. + * 2.
