This tweet showcases XSS bypass payloads for Imperva WAF. The payloads include variations of onfocus event manipulation to execute JavaScript code. These payloads can potentially bypass Imperva WAF's protection against XSS attacks. The first payload retrieves the user's cookie and writes it to the document, while the others execute alert functions. Imperva WAF users should be aware of these bypass techniques and ensure their security measures are updated to mitigate such vulnerabilities.
