Security risk: 
Moderately critical 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Cross site scripting
Affected versions: 
<1.3.0
Description: 

This module enables you to create facet-filters for results of a search query and exposes them as blocks

The module doesn't sufficiently escape HTML under the scenario leading to a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by two factors. First, an attacker must have a way to insert results in the dataset that is exposed as a facet before this can happen. The permission to inject malicious strings depends on the site's search configuration but could be available to any user who can create content in a site. Second, the site must be using the Javascript-based dropdown widget.

Solution: 

An effective mitigation is to change the widget to use links instead of the dropdown widget.
