Cursor's Workspace Trust is disabled by default. A hidden runOn: folderOpen task can exfiltrate your .env before you finish your coffee.

A researcher found a Lovable app with 18,000 users leaking names, emails, debt amounts, and home addresses. The root cause: public client access plus weak RLS policy enforcement.

A founder shipped a gorgeous v0 interface connected to Supabase without enabling access controls. Visitors could query records they were never supposed to see.
