Stored XSS via unescaped Base Font Size

Published May 1, 2025 · Updated May 1, 2025

Stored XSS in WP Maps before 4.7.2 allows remote authenticated users with admin access to execute scripts through crafted map settings. The Base Font Size field stores closing-style-tag and event-handler markup without sufficient sanitization or output escaping. The security boundary is relevant when unfiltered_html is disabled, including multisite; a viewer triggers the payload by loading the map.
