CVE-2024-3636Public exploitNetwork attack vector

Stored XSS via unescaped template names

Published Aug 5, 2024 · Updated Aug 7, 2024

Stored XSS in Pinpoint Booking System before 2.9.9.4.8 allows remote authenticated users with admin access to execute script in browsers. The email and SMS template editors store the Name field without sanitizing it and render the saved value without escaping, so script markup executes when the page is revisited. Administrator access is required, and the issue remains reachable when unfiltered_html is disabled, including in WordPress multisite deployments.
