WordPress Plugin Vulnerabilities
Smash Balloon Social Post Feed < 4.1.6 - Contributor+ Stored XSS
Description
The plugin does not validate and escapes some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as a contributor to perform Stored Cross-Site Scripting attacks against logged-in admins.
Proof of Concept
1. Connect Facebook and a Facebook Page to the plugin. 2. Exploit shortcode: [custom-facebook-feed feed='1' class='" onmouseover="alert(1)"']
