CVE-2024-11503Public exploitNetwork attack vector

Stored XSS via unescaped typography margin setting

Published Mar 25, 2025 · Updated Mar 25, 2025

Stored XSS in ShapedPlugin Smart Tabs before 2.2.7 allows remote authenticated users with administrator rights to execute JavaScript. The Typography settings handler stores an unsanitized sp_tab_shortcode_options[sptpro_section_title_typo][margin-bottom] value and renders it unescaped into the field. Exploitation requires an administrator whose unfiltered_html capability is disabled and a user to load the settings page and mouse over the crafted field.
