Vulnerability from drupal

Published

Modified

2026-05-13 17:18

Summary

Details

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.
