Auth Check Only in Client Code

The auth gate runs only in a client component (a useEffect redirect or conditional render), so an attacker can bypass it by calling the API route directly.

IDOR Vulnerability on REST Endpoint

A REST endpoint returns resources by id without checking the caller owns them, so any signed-in user can read another user's data by changing the id.

Missing Row Level Security on Supabase Table

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

Secret API Key Exposed in Client Bundle

A sensitive key (Stripe secret, OpenAI, Supabase service role) has a NEXT_PUBLIC_ prefix, so it is inlined into the browser bundle for anyone to read.
