WordPress Plugin Vulnerabilities

CPT Bootstrap Carousel <= 1.12 - Contributor+ Stored XSS via Shortcode

Description

The plugin does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

Proof of Concept

Note: First you need to add a Carousel.

Exploit shortcode:

[image-carousel interval='" onmouseover="alert(1)"']
