From fcee09d89d008d2dba07c213b66481a222bfaed7 Mon Sep 17 00:00:00 2001 From: Oleg Date: Wed, 13 May 2026 00:43:46 -0700 Subject: [PATCH] feat(boot_guards): refuse to start in web mode with insecure config (#441) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR-5 of the #433 web-exposed hardening track. Loud-failure boot-time checks for the obviously-unsafe configurations an internet-exposed deployment must not run with. Stacked on #475 → #474 → #473 → #472. Scope of this PR ================ Ships the guards that don't depend on unshipped pieces of the track. The remaining guards land alongside their owning PRs (admin user, legacy UI password → #435; multi-worker rate-limit backend → #438; audit emission for overrides → #440). Each deferral is marked with a TODO referencing the owning PR. Guards (fatal, web mode only) ----------------------------- * SESSION_SECRET — PINKY_SESSION_SECRET unset, < 32 chars, one of a small placeholder set (changeme/secret/pinky/...), or trivially low-entropy (≤ 2 distinct chars). * PUBLIC_BIND_NO_TLS — bound to 0.0.0.0 / a non-loopback host without PINKY_BEHIND_TLS_PROXY=true to acknowledge upstream TLS termination. * MISSING_TRUSTED_PROXIES — PINKY_BEHIND_TLS_PROXY=true with PINKY_TRUSTED_PROXIES empty; otherwise audit + rate-limit attribution silently flatten to 127.0.0.1 because #442's resolver refuses to honor XFF from an untrusted peer. * DB_PERMISSIONS — DB file or its parent directory has loose permissions (group/other bits set). No-op on Windows. Warnings (non-fatal, all modes) ------------------------------- * RUNNING_AS_ROOT — daemon process UID == 0. Override mechanism ------------------ Per-guard PINKY_ALLOW_INSECURE_=true env vars. **No global escape hatch by design** — operators who need to bypass a guard for an emergency must do so per-guard, and each override is logged loudly at startup. Once #440 lands, overrides will also emit an audit event. Wiring ------ * assert_web_mode_safe(mode, host, db_path) called from pinky_daemon.__main__._run_api after argparse + mode resolution and before uvicorn.run. * Failure → preformatted rejection block to stderr; sys.exit(3). Distinct exit code from invalid-mode (#434 uses 2) so wrapper scripts can route on it. Tests (34 new) -------------- * check_session_secret: unset / short / placeholder (parametrised) / long-random-passes / low-entropy / override. * check_public_bind_requires_tls_marker: loopback variants pass / public bind no marker fails / public bind with marker passes / specific public address fails / override. * check_trusted_proxies_when_behind_tls: no marker passes / marker with proxies passes / marker without proxies fails. * check_db_permissions: nonexistent skips / secure dir + file pass / world-readable dir + file fail. * run_warning_guards: empty list when nothing to warn / running as root warning / silenced by override. * assert_web_mode_safe: trusted/lan skip all / web all-pass / web aggregates failures / overrides let boot proceed. * format_guard_error: contains all expected sections. Closes part of #433.
