CVE-2021-24708Public exploitNetwork attack vector

Stored XSS via unescaped export friendly name

Published Nov 8, 2021 · Updated Aug 3, 2024

Stored cross-site scripting in Breakdance WP All Export before 1.3.1 allows remote authenticated users to execute scripts via a crafted export name. The Manage Exports settings page renders the saved Friendly Name field without HTML escaping, turning stored markup into executable browser content. Administrator-level access to rename an export and a later visit to Manage Exports are required; execution occurs even when unfiltered_html is disabled and is limited to the visiting user's browser session.
