The tweet discusses a bypass for Web Application Firewalls (WAF) to execute cross-site scripting (XSS) attacks. The bypass involves reflected XSS into HTML context with most tags and attributes blocked. This can be a significant security issue for websites protected by WAF. A blog post should be created to detail the technique used for the bypass, its implications on web security, and how organizations can mitigate such vulnerabilities.
