The tweet mentions manually finding the exact number of bytes required for a SQL Injection payload to bypass Modsecurity (nginx WAF). This is a significant discovery as it indicates a potential vulnerability in the WAF. A blog post should be made detailing the vulnerability, the specific bypass payload, and the implications for Modsecurity users. Include technical details on how the bypass works and provide recommendations for securing against such attacks.
