CVE-2021-24424Public exploitNetwork attack vector

Authenticated stored XSS via unsanitized snapshot data

Published Jul 12, 2021 · Updated Aug 3, 2024

Cross-site scripting in WebFactory Ltd WP Reset before 1.90 allows remote authenticated users to execute script via snapshot creation. The admin dashboard accepts the extra_data parameter without sanitizing or escaping it, then stores the value in snapshot data rendered later in the dashboard. Exploitation requires an authenticated WordPress account able to create snapshots and a victim browser loading the affected dashboard view, enabling script execution in that administrative context without a reported availability impact.
