This module enables you to add autocomplete suggestions for search forms created with the Search API module.
The module ships with a test script that is accessible to anonymous users and doesn't sufficiently validate user input, leading to a Cross Site Scripting vulnerability.
This vulnerability is mitigated by the fact that the web server must be configured to display warning messages to users.
