Public Supabase Storage bucket
Anyone can list the contents of this Storage bucket without signing in, so every file it holds can be enumerated and downloaded.
Why it matters
Anyone can list the contents of this Storage bucket without signing in, so every file it holds can be enumerated and downloaded. Public buckets are a legitimate feature — the question is whether you meant this one to be public, and whether anything user-uploaded ended up in it.
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.
One or more Supabase Storage buckets have public read enabled, so anyone can list and download their contents. Public buckets are a legitimate feature (e.g. public avatars) — verify nothing private is stored in them, and set any bucket holding user or sensitive files to private with RLS-based access policies.
