New Web challenges : client & server

Here is a new series of client and server web challenges.
In this series, you will learn about sometimes little-known vulnerabilites, namely an introduction to Web Socket security, a first challenge about Prototype Pollution in NodeJS and an advanced PHP object deserialization.

• Web Socket - 0 protection
• NodeJS - Prototype Pollution Bypass
• PHP - Unserialize Pop Chain

Thank you Worty for those new challenges!
