The tweet mentions an attempt to bypass the Vercel WAF in the context of a $50k bug bounty program. However, no specific payload or vulnerability type is provided. The tweet implies a universal bypass attempt given the nature of WAF bypass research, but lacks technical specifics.
Vercel WAF is deployed to protect applications hosted on Vercel's platform, often guarding against common web attacks like XSS, SQL Injection, RCE, and others. Bypassing such WAFs can be critical for security researchers to demonstrate vulnerabilities that need fixing.
Without a specific payload or detailed explanation, this tweet is more of an announcement or demonstration of effort rather than a technical guide or exploit. Researchers aiming to bypass the Vercel WAF should test various payloads targeting known vulnerabilities, try obfuscation techniques, URL encoding, and other evasion tactics to find weaknesses in the WAF rules.
If detailed payloads or techniques are discovered, sharing them with the community can help improve the security posture of Vercel and similar platforms.
