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.

Convert requireSession -> requireSessionOrApiKey across recipes,
collections, meal-plans, shopping-lists, pantry, feed, and ai/*
(52 routes) so API keys work end-to-end, not just for the handful of
endpoints that supported them before. Scope was explicitly confirmed
per-resource-family with the user before any file was touched.
Left session-cookie-only, deliberately: users/me*, ai-keys/*,
webhooks/*, conversations/*, notifications/*, push/subscribe, admin/*
— account/credential-adjacent surface that shouldn't widen without a
separate, explicit decision.

Both chat panels (per-recipe and the general cooking assistant) previously
kept messages in component state only — closing the sheet or reloading
the page lost everything. Both POST routes now persist question+answer
pairs to a new chat_messages table (recipeId null for the general
assistant), and both panels load their own history back on open.
New GET /api/v1/ai/chat-history (scoped by recipeId, or scope=general for
the homepage assistant, or neither to search across everything) backs a
new search control in both panels' header — debounced, shows matched
messages with date and (when searching across everything) which recipe
they belonged to.
Verified locally: asked a real question, closed and reopened the panel
and confirmed the conversation reloaded, then searched a keyword from
that conversation and confirmed both the question and answer surfaced
in the results dropdown.
Moved the homepage cooking-assistant button from bottom-24 to bottom-16 —
still clears the recipe list's floating bulk-action bar, just not as far.
Both chat system prompts (cooking-chat and the per-recipe chat) now
explicitly identify as "Epicure" and are told never to name the underlying
model/provider if asked — previously they'd just answer honestly with
whatever the model calls itself.
Verified locally: screenshotted the new button position, and asked "what
model or AI are you" through the real UI — response identified as Epicure
with no model name.
The existing recipe chat (RecipeChatPanel) is tightly scoped to one
recipe — recipeId is required and its system prompt embeds that recipe's
full ingredient/step context. Added a sibling, not a modification: a new
floating assistant on the recipes list page for questions that aren't
about any specific recipe (technique, substitutions, timing, food safety).
New /api/v1/ai/cooking-chat route (same quota/rate-limit/model-resolution
pattern as recipe-chat, minus the recipe lookup) and CookingAssistantPanel
component (same floating-button + Sheet UI). Positioned at bottom-24
rather than bottom-6 so it doesn't sit in the same band as the recipe
list's floating bulk-action bar during select mode.
Verified locally: asked a real cooking question through the actual UI,
got a correctly-formatted markdown answer with no recipe context leaking
in (confirmed the request payload only carries the question, no recipeId).
