From the whole-codebase re-audit (deferred MEDIUM findings, Codex-reviewed):
- poller: CredentialVault enforces a credential's disabled_at lock only at connect(), but
PollMetrics reuses one long-lived SSH connection per server, so a credential disabled
mid-run kept streaming metrics over the already-open session. Add Server::withActiveCredential()
(whereHas credential whereNull disabled_at); the poller selects via it and prunes any cached
client whose server left the active set, so a revocation drops the server on the next tick and
closes its session promptly.
- prod compose: add security_opt no-new-privileges:true to every service + a generous pids_limit
(fork-bomb backstop). cap_drop/read_only are deliberately left out — they need a per-service
prod smoke test (nginx :80 bind, entrypoint chown) before enabling; documented inline.
- Caddyfile + compose: strengthen the TRUSTED_PROXY_CIDR guidance — an over-broad value in
external-TLS mode lets any client forge X-Forwarded-For and defeat the IP-keyed throttles + ban.
