Description

The GetResponse Forms by Optin Cat plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.5.7. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • fatcatapps GetResponse Forms by Optin Cat — Up to and including 2.5.7
  • fatcatapps getresponse_forms — Up to and including 2.5.6
