A path traversal issue exists in the Supabase node where the `tableId` parameter is inserted into request paths without proper validation. This allows attackers to exploit workflows that bind `tableId` to untrusted input to access Auth and Storage APIs using the administrative `serviceRole` key. This action bypasses Row Level Security (RLS), which is a security feature that restricts which rows of data a user can see or modify, leading to unauthorized data access and modification.
