CVE-2021-24445Public exploitNetwork attack vector

Stored XSS via unescaped audit names

Published Aug 16, 2021 · Updated Aug 3, 2024

Stored XSS in 99 Robots My Site Audit 1.2.4 and earlier allows remote authenticated users to execute JavaScript via an audit name. The audit-creation path stores the Audit Name without sanitizing it, and the All Audit and Dashboard pages render that value without escaping. A high-privilege account can plant the payload even when unfiltered_html is disabled; opening either page executes it in the viewer's browser.
