Name of the Vulnerable Software and Affected Versions GDPR cookies module for Backdrop CMS versions prior to 1.x-1.3.5

Description The GDPR cookies module fails to sufficiently protect visitors from Cross Site Scripting (XSS), which occurs when a malicious value is provided for the optional Info content field associated with the YouTube service. Exploitation requires the attacker to possess a role with the "Create a GDPR Cookies Service" or "Edit any GDPR Cookies Service" permission, and the site must have a YouTube service configured.

Recommendations Update the GDPR cookies module for Backdrop CMS to version 1.x-1.3.5 or later.
