The tweet mentions a user named @zemnmez who is trying to find a third bypass for Vercel's Web Application Firewall (WAF). It shows some frustration in successfully bypassing Vercel's WAF but otherwise indicates things are fine. There is no mention of specific vulnerabilities like XSS or SQLi or any bypass payload in the tweet. This suggests the attempt is about discovering new methods to bypass Vercel's WAF protections. Without specific payload details, the analysis remains high level, highlighting the ongoing challenge security researchers face in finding bypass techniques for Vercel's WAF system.
