Description
The affiliate-toolkit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the product link and image URL fields in all versions up to, and including, 3.9.2. This is due to insufficient input sanitization and output escaping: the URL values were stored as submitted and placed into href, onclick and img src attributes without escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts into products. The scripts run whenever a user views or previews a page where the product is displayed, for example through the [atkp_product] shortcode.
