This tweet appreciates WAF bypass techniques used in the React2Shell tool, which are helpful for bug bounty hunters. React2Shell is a tool designed to bypass Web Application Firewalls (WAFs) effectively. The techniques likely cover various types of vulnerabilities, hence the universal application. Bug bounty hunters can leverage these methods to test the security of web applications and discover vulnerabilities that are hidden behind WAF protections. The mention implies that these bypass methods are practical and effective in real-world scenarios, aiding security researchers in finding vulnerabilities such as Cross-Site Scripting (XSS), SQL Injection (SQLi), Remote Code Execution (RCE), and more, that WAFs typically try to block.
