Mass assignment vulnerabilities occur when an API binds user-submitted data directly to an internal model without filtering. This allows attackers to modify fields they shouldn't access, like adding isAdmin: true to a JSON payload. The bug is common in frameworks that simplify object creation from request bodies.
A classic bug modern ORMs still make dangerously easy to write. Whitelist API parameters to prevent users from self-assigning admin roles.
