Full list of the audit's confirmed findings and their fixes: - Stored XSS via unescaped JSON-LD on the public recipe page (app/r/[id]/page.tsx) — escape < before injecting. - CSP allowed unsafe-eval in production — now dev-only (Next prod never eval()s; only its HMR does). - avatarUrl accepted any URL with no ownership check — now takes an avatarKey issued by avatar-presign, validated server-side, same pattern as recipe/review photos. - No session revocation on password change/reset — both now revoke other sessions (revokeOtherSessions: true, revokeSessionsOnPasswordReset). - Rate-limit bypass via spoofable X-Forwarded-For — take the last (proxy-appended) hop instead of the first (client-supplied) one, matching the single-Traefik-hop topology. - Webhook signing secrets stored plaintext — now AES-256-GCM encrypted like every other secret in this app, with a legacy- plaintext fallback for pre-existing rows (bare hex has no ":", our ciphertext format always does). - Better Auth's own rate limiter defaulted to in-memory storage, ineffective across replicas — now backed by the same Redis as lib/rate-limit.ts (secondaryStorage), with storeSessionInDatabase explicit so session storage itself doesn't move as a side effect. - Presigned upload URLs didn't bind the declared file size to the actual upload, letting a client under-declare size (and quota charge) then PUT an arbitrarily large object — switched to S3 presigned POST with a signed content-length-range condition, enforced by the storage server itself. - generateMetadata() on the recipe page skipped the visibility filter the page body uses, leaking a private recipe's title via <title> to any signed-in user with the id. - Block/unblock had no rate limit, unlike follow/unfollow. - AI quota was charged even when a user's own BYOK key was used (their own credentials/billing) — added an isByok flag through the config-resolution chain and skip the charge when set. Also wired BYOK into generate/generate-from-idea/translate/import-url, which never looked it up at all before. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
