Vulnerability Overview

The Feed Them Social plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘access_token’ parameter in the function fts_instagram_token_ajax in versions up to, and including, 2.9.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, subscriber and above, to inject arbitrary web scripts stored in the plugin options.
