Auth Check Only in Client Code

The auth gate runs only in a client component (useEffect redirect or conditional render), which an attacker bypasses by disabling JavaScript or hitting the API route directly.

IDOR Vulnerability on REST Endpoint

A REST endpoint returns resources by id without verifying the caller owns that resource. Any authenticated user can access any other user's data by changing the id in the URL.

A public Supabase table has RLS disabled or has an overly permissive policy, meaning any authenticated user can read or modify every row regardless of ownership.

Secret API Key Exposed in Client Bundle

A sensitive credential (Stripe secret, OpenAI API key, Supabase service role key) is prefixed with NEXT_PUBLIC_, causing it to be inlined into the browser JavaScript bundle where anyone can read it.
