Download Top 25 Social Icons <= 3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode

Description

The Top 25 Social Icons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode in all versions up to, and including, 3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level and above permissions, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
