VIR risk

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.
