Project: Colorbox [1]
Date: 2025-April-23
Security risk: *Moderately critical* 14 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
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 [3]
  * If you use the Colorbox module 2.0.x, upgrade to Colorbox 2.1.3 [4], as
    the 2.0.x branch becomes unsupported.
