The .7z file contains the application's backend logic, often written in or Python (Flask/Django) . By analyzing the code, researchers look for:
An attacker sends a JSON payload containing the __proto__ key. This allows them to inject properties into the global object prototype, effectively changing the behavior of the entire application. 3. From Pollution to Remote Code Execution (RCE) moanshop.7z
Once the attacker can "pollute" the global object, they target specific application behaviors to gain control: moanshop.7z
