Project: Colorbox Inline [1]
Date: 2026-May-13
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross-site scripting

Affected versions: <2.1.1
CVE IDs: CVE-2026-8493
Description: 
This module enables you to open content already on the page within a
colorbox.

The module doesn't sufficiently sanitize the data-colorbox-inline attribute
value before passing it to jQuery, leading to a Cross-Site Scripting (XSS)
vulnerability.

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 Inline module for Drupal 8.x, upgrade to Colorbox
   Inline 2.1.1 [3]
