This tweet talks about a WAF bypass related to Stored Cross-Site Scripting (Stored XSS) vulnerabilities. Stored XSS is a type of security flaw where malicious scripts are stored on a target server and executed in the context of a user's browser. The tweet praises the WAF bypass as perfect but does not provide specific details about the payload used or the WAF vendor involved. No explicit technical details are shared in the tweet. Stored XSS bypassing a Web Application Firewall (WAF) is significant in bug bounty and cybersecurity communities because it can allow attackers to deliver persistent malicious scripts that evade detection and remain active.
