Rich Table of Contents < 1.3.9 - Contributor+ Stored XSS

The plugin does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

PoC

Note: The shortcode generates the content based on the h2 tags, so the heading tags must also be specified. Please use the Classic editor » text area to paste the content:

title

[rtoc_mokuji frame_design=‘" onmouseover=“alert(1)”’ list_h2_type=‘round’ heading=‘h2’]
