WordPress Plugin Vulnerabilities
Custom Post Type List Shortcode <= 1.4.4 - Contributor+ Stored XSS
Description
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.
Proof of Concept
Note: First you need to add a Post Category with a following name: " onmouseover="alert(1)" Note: Second you need to add a Post with the exploit category. [cpt_list post_type='post' category='" onmouseover="alert(1)"']
