Description

The GDPR cookies module for Backdrop CMS (before <br /> <br /> 1.x-1.3.5) doesn&amp;#39;t sufficiently protect visitors from Cross Site Scripting (XSS) if a malicious value has been provided for the optional &amp;#39;Info content&amp;#39; field for the YouTube service. This is mitigated by the fact that an attacker must have a role with the permission "Create a GDPR Cookies Service" or "Edit any GDPR Cookies Service" and a site must have added a YouTube service as configuration.
