CVE-2026-108514 · Severity: info · Published 2026-10-30

Drupal's Navigation module, a core content management system component, fails to properly sanitize certain HTML attributes in menu items, allowing attackers to inject malicious scripts. An attacker must have permission to edit HTML tags with specific data attributes or administer menus to exploit this. Successful exploitation could result in script execution within the context of an administrator or other authorized user's browser session.

## Technical details

The Navigation module does not sufficiently sanitize data attributes in HTML tags, creating a stored XSS vulnerability. Exploitation requires the attacker to have a role with permission to enter HTML tags containing specific data attributes, or the administer menu permission, making this a privilege-escalation scenario. The vulnerability affects Drupal core versions 10.3.0–10.6.18, 11.0.0–11.3.18, 11.4.0–11.4.9, and 12.0.0-alpha1–12.0.0-beta1.
