Last modified

CVE-2025-71310 is a low-severity vulnerability rated 1.8/10 on the CVSS scale. The GDPR cookies module for Backdrop CMS (before 1.x-1.3.5) doesn't sufficiently protect visitors from Cross Site Scripting (XSS) if a malicious value has been provided for the optional 'Info content' 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.. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
