Follow Us Badges < 3.1.11 - Authenticated (Contributor+) Stored Cross-Site Scripting via wpsite_follow_us_badges Shortcode

Description

The Follow Us Badges plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpsite_follow_us_badges shortcode in all versions up to, and including, 3.1.10 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
