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)

Identifies a vulnerable merge function in the cart.js or admin.js file. From Pollution to Remote Code Execution (RCE) Injecting

While the exact details can vary depending on the specific competition (e.g., SECCON, HTB, or private bug bounty simulations), the typical write-up for this challenge focuses on three main stages:

Overwriting settings in the rendering engine (like EJS or Pug) to force the server to execute malicious system commands. Summary of the Solution To solve the challenge, a researcher typically: Downloads and extracts the moanshop.7z file.
