Missing rls
This table answers unauthenticated read requests from anyone on the internet.
Why it matters
This table answers unauthenticated read requests from anyone on the internet. The anon key needed to query it is published in your own JavaScript, so finding it takes no skill — every row can be downloaded in bulk. This is the single most common critical failure in Supabase-backed apps, because RLS is off by default and nothing in the client warns you.
How ShipReady detects it
Tests whether a Supabase project is readable by anyone. The project URL and anon key are read from the page's own JavaScript — both are published there by design. The anon key is then used exactly as a browser would use it, against common table names, and a table is reported only when it returns actual rows. Returning an empty array is not a finding: that is what correctly configured RLS looks like. Observed rows are, because they prove the data is readable by whoever holds a key that is already public. The probe sequence is memoised on the discovered project, so a project referenced by ten pages is tested once rather than ten times.
Detection is deterministic. ShipReady reports this only when it observes the condition directly, and prefers to miss a real problem over inventing one. Rule version 1.2.0.
How to fix it
This is the prompt ShipReady puts in your report — written to be pasted straight into Cursor, Claude Code, or whichever assistant built the app.
Row Level Security (RLS) is either missing or overly permissive for the '{table_name}' table. Anyone with the anon key can read its contents. Enable RLS and define strict policies.Frequently asked questions
- What does "Missing rls" mean?
- This table answers unauthenticated read requests from anyone on the internet.
- How serious is it?
- ShipReady rates this critical. Fix before launch. On its own, this is enough to compromise the application.
- How do I fix it?
- Paste the fix prompt on this page into Cursor, Claude Code or your AI editor. It is the same prompt ShipReady puts in your report.
- Can I check my own site?
- Yes — ShipReady scans up to ten pages of any public site for free and reports this alongside every other check.
