Prototype pollution attack

Anyone tell me how to hunt prototype pollution attack already i tried this but no improvement. anyone tell

Prototype pollution vulnerabilities occur when the code of the application allows the alteration of any prototype properties, usually those of the Object prototype . By inserting or modifying a property of a prototype, all inherited objects based on that prototype would reflect that change, as will all future objects created by the application.
