Replit · Supabase RLS check

Does your Replit app protect its Supabase data with real RLS rules?

Replit's Agent scaffolds a working app inside a full cloud IDE and can deploy it straight from the same workspace, often to a live .replit.app URL.

Database rules are flagged as not-tested on every URL scan — a connected repo scan reviews your migrations and policy files directly instead.

What we look at for Replit

The checks that matter most for Replit apps.

Wardloom always runs the full catalogue — these are the ones Replit projects most often get wrong, based on how the tool tends to generate and deploy code.

Auth and session flaws

We review weak JWT secrets, missing rate limits, and insecure session patterns that show up in code and config.

Login is the front door. Soft session handling is how accounts get guessed, replayed, or shared without you noticing.

Dependency CVEs

We scan your dependency tree for known-vulnerable or abandoned packages that still ship with the app.

Most vibe-coded stacks inherit risk from npm. Known CVEs are public; attackers do not need inventiveness, only an unpatched install.

Env and config exposure

We look for server-only secrets used in the client, exposed dotfiles, and keys that belong behind the server wall.

AI scaffolds often put REACT_APP_ or NEXT_PUBLIC_ in front of secrets by habit. Config exposure is how private settings become public pages.

Common Replit mistakes

What builders miss with Replit.

  • Replit Agent can scaffold a Supabase-backed app quickly, but RLS is a manual step it doesn't always take.
  • A workspace with public read access enabled during development is easy to forget to lock down.
  • Database migrations generated by the Agent don't always include the policy files that would show RLS is on.

What a scan like this can't see

Wardloom is honest about its limits. Database rules (Firestore RLS, Supabase RLS) is not something a read-only scan can verify from the outside — it requires a connected repo scan or a manual review. A clean result means nothing visible was wrong, not that everything was checked.
