  "account": "Supabase service-role key exposure in browser code poses serious security risks. This key, when used in client-side code, grants unrestricted access to an entire database, enabling unauthorized read, modify, and delete operations. AI-powered development tools, seeking to bypass Row Level Security (RLS) policies, often default to using the service-role key, which is then inadvertently shared with all website visitors. To mitigate this vulnerability, developers should exclusively utilize the anon key in browser applications and ensure the service-role key remains confined to server-side code, such as API routes or server actions. Supabase users can rotate their service-role key through the platform's settings or request assistance from AI development tools designed to rectify such security issues. For a comprehensive guide on resolving this issue, visit launchpad.axonscape.com/fix/supabase-service-role-key-in-browser.",
  "summary": "The service-role key skips every Row Level Security rule. Used in browser code, it's handed to every visitor, who can then read, change or delete your whole database. What you see Code that runs in the browser creates a Supabase client with SUPABASE_SERVICE_ROLE_KEY (or a key whose role is service_role ). Why it happens AI tools reach for the service-role key when a query is blocked by RLS: it…",
