The tweet shares two links to blogs that likely discuss methods for bypassing WAF (Web Application Firewall) protections. Although the exact vulnerability type and WAF vendor are not explicitly mentioned, the tweet suggests resources for learning about bypass techniques that could be relevant across multiple WAF platforms and for different types of vulnerabilities (hence the classification as UNIVERSAL). These blogs may contain various bypass payloads, technical details, and explanations for bypassing security rules enforced by WAFs. Sharing such knowledge helps security researchers and penetration testers improve defensive measures and understand common bypass methods used in the wild. Without direct access to the content of the links, a detailed technical analysis is not possible here. However, the tweet highlights the importance of continuous research and information sharing in the WAF security community.
