View online: https://www.drupal.org/sa-contrib-2019-030 Project: Facets [1] Version: 8.x-1.x-dev Date: 2019-February-27 Security risk: *Moderately critical* 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Cross site scripting 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:  * Install the latest version Facets 8.x-1.3 [3] An effective mitigation is to change the widget to use links instead of the dropdown widget.
