Security risk: 
Moderately critical 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All
Vulnerability: 
Cross Site Scripting
Affected versions: 
<2.1.3
CVE IDs: 
CVE-2025-3900
Description: 

Colorbox is a module that allows Images, and iframed or inline content to be displayed in a modal above the current page.

The Colorbox module doesn't sufficiently sanitize data attributes before opening modals.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes.

Solution: 

Install the latest version:

  • If you use the Colorbox module 2.1.x for Drupal 10 or above, upgrade to Colorbox 2.1.3
  • If you use the Colorbox module 2.0.x, upgrade to Colorbox 2.1.3, as the 2.0.x branch becomes unsupported.
