WordPress Plugin Vulnerabilities

YourChannel: Everything you want in a YouTube plugin < 1.2.3 - 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

Exploit shortcode:

[yourchannel video='" onmouseover=alert(1) "']

Affects Plugins

Fixed in 1.2.3
