The tweet highlights the challenge in web application security of effectively blocking Cross-Site Scripting (XSS) attacks using Web Application Firewalls (WAFs). It suggests that simply blocking every known XSS payload is not enough to ensure security. Instead, it emphasizes the importance of creativity and skill in bypassing WAF protections to identify vulnerabilities. This reflects a deeper understanding and mastery in application security where security professionals think beyond predefined patterns and adapt to new techniques to test the robustness of WAFs. Essentially, it praises the ingenuity required for WAF bypass, which is a critical skill for discovering and addressing real security weaknesses.
