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.
