Supabase Service Role Key Check — Is Your Admin Key in Browser Code?
DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.
What the issue is
Your Supabase service-role (admin) key in code that isn't server-only gives anyone who finds it full database control — bypassing RLS entirely.
Why AI tools generate it
AI builders reach for the service-role key 'to make it work' and place it in client code, not realizing this key must never touch the browser.
How DevMeth detects it
A code scan looks for service-role key patterns and flags any that appear in client-visible (non-server) code, reporting the masked location.
Your Supabase admin key (service role) is in code that isn't server-only
WHAT WE FOUND
src/lib/supabase.ts — service_role …z8w1 (masked)
The fix, in three steps
Move the service-role key to a server-only secret, keep admin database access behind a server endpoint, and rotate the key. Three steps with a guardrail.
Run a free scan and each finding carries a paste-ready fix prompt you can act on.

What can the service-role key do?
It bypasses Row Level Security entirely, giving whoever holds it full read/write over your database. It must never appear in client code.
How do I know if it's exposed?
The scan flags service-role key patterns that appear in browser-visible code and reports their masked locations.
What's the fix?
Rotate the key, keep it in a server-only environment variable, and route admin operations through a server endpoint.
