The tweet by @xchopath is asking if there is any resource to learn how to bypass the regex rules of a WAF or if the source code is available. However, no specific payload or detailed information about a particular bypass or WAF vendor is provided. The query is essentially about learning or finding resources for bypassing regex-based rules in web application firewalls. Unfortunately, without specific technical details or a payload, a detailed analysis or blog post cannot be created. If any payload or more details about the vendor and type of bypass are provided, a more thorough analysis can be done.
