CVE ID :CVE-2025-71310

Published : May 26, 2026, 1:06 a.m. | 50 minutes ago

Description :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.

Severity: 1.8 | LOW
