Browser Screenshots < 1.7.6 - Contributor+ Stored XSS

Description

The plugin allowed authenticated users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks as the image_class parameter of the browser-shot shortcode was not escaped.

Proof of Concept

Add the following shortcode in a page, then view the page (either published or as preview to trigger the XSS): [browser-shot url="https://example.com" image_class='" onload="alert(origin)'] 

Affects Plugins

browser-shots
Fixed in version 1.7.6
