Addresses the findings from the platform security audit. Verified green:
all-workspace typecheck, web build, 16 API unit tests, 23 e2e auth tests,
and 0 high/critical production dependency vulnerabilities.
Dependencies (High):
- Bump drizzle-orm 0.36→0.45.2 (GHSA-gpj5-g38j-94v9 SQLi-via-identifier)
and drizzle-kit→0.31.10; npm audit fix cleared fast-uri path-traversal
and the react-router open-redirect. Remaining audit items are dev-only
build tooling (esbuild/vite), not shipped at runtime.
AI cost control + storage quota (new ai_usage table, migration 0002):
- Per-firm monthly AI token budget enforced before each completion (429),
with every completion recorded to an ai_usage ledger (lib/ai-usage.ts).
- Enforce per-plan storage quota on upload (402) and maintain
storage_bytes_used on upload/delete (lib/storage-quota.ts); widen the
column int→bigint so 8GB/50GB plans don't overflow.
Auth (defense-in-depth):
- Constant-time login: verify against a dummy argon2 hash when the account
doesn't exist, closing the timing/enumeration oracle (verifyPasswordSafe).
- Enforce suspension on requireSuperadmin, /auth/me, /auth/resend-verification.
Web:
- Validate the post-login ?next= redirect to same-origin paths only
(open-redirect / phishing).
Deploy hardening:
- docker-compose: memory/CPU limits so a spike can't OOM the Dokploy host.
- .dockerignore: keep destructive one-off scripts (seed-demo, create-admin,
migrate-storage) out of the runtime image; retain the cron scripts.
- seed-demo.ts: hard-refuse NODE_ENV=production and the prod DB host.
Webhooks / config:
- Stripe idempotency via a stripe_events ledger (skip already-processed
events; record only after successful processing so a transient failure
still retries); make the plan-upgraded email non-blocking.
- Rate-limit account export and invoice PDF; cap invoice item arrays at 200.
- Require TURNSTILE_SECRET_KEY in production (bot protection no longer fails
open on a forgotten key); don't load .env under NODE_ENV=test so the suite
is hermetic.
