Independent adversarial audit verdict was NOT SAFE; fixed:
- P0-1 /auth/confirm no longer trusts the query `type` (pinned to
'email_change'); a public endpoint feeding an attacker-chosen OTP
type into verifyOtp was an unintended auth entrypoint.
- P0-2 email sync uses the verifyOtp response user, not a follow-up
getUser() that may not reflect the just-verified identity; /me now
reconciles space_members.email against the authoritative auth email
on load, so a missed sync self-heals (no permanent stale email).
- P1-1 requestEmailChange builds the confirm origin from
NEXT_PUBLIC_APP_URL only, never request headers (forged Host could
redirect the confirmation link / capture token_hash).
- P2-1 isSecretConfigField also catches password/token/private_key/
*_token/*_password so non-conventionally-named credentials can't be
stored in plaintext integrations.config.
521 tests; build clean.
PayPal client_secret (and any secret-named integration field) was stored
plaintext in integrations.config, unlike Stripe/door which use the
AES-256-GCM vault. A DB read or backup leaked it in cleartext.
- lib/secrets/vault.ts: canonical generic storeSecret/readSecret +
isSecretConfigField (the proven Stripe vault logic, generalized).
- saveIntegration: secret-named fields go to the vault, only a *_ref is
kept in config; blank submit preserves the ref (write-only like
Stripe); legacy plaintext auto-migrates into the vault on next save.
- paypal/sync reads client_secret from the vault, transitional fallback
to legacy plaintext until the next save.
- Docs updated (API_REFERENCE, ARCHITECTURE 10.3). 502 tests.
The .gitignore rule `secrets/` matched any directory named secrets/
anywhere in the tree, including the new lib/secrets/ application code
that holds the AES-GCM helpers. Production build failed with
"Module not found: Can't resolve '@/lib/secrets/crypto'". Anchor the
ignore to the repo root with `/secrets/` so only the top-level
credentials directory is excluded.
