The tweet highlights an important security lesson related to Web Application Firewalls (WAFs). It points out that encountering a 403 Forbidden response from a WAF should not be the end of testing or exploration. The user implies that there exists a bypass method which is detailed in the linked Medium article. The lesson is metaphorical: even if a WAF blocks direct access with a 403 error, attackers or testers should continue to investigate alternative methods to access or test the application. The exact WAF vendor, type of vulnerability, and specific payload for the bypass are not provided in the tweet itself. For a full technical explanation and step-by-step breakdown, the user has shared a Medium article link for readers to check out.
