Name of the Vulnerable Software and Affected Versions Drupal Colorbox Inline versions 0.0.0 through 2.1.0

Description An issue in the Drupal Colorbox Inline module, which allows opening page content within a colorbox, occurs because the module does not sufficiently sanitize the data-colorbox-inline attribute value before passing it to jQuery. This leads to Cross-Site Scripting (XSS), a flaw where malicious scripts are injected into trusted websites. Exploitation requires the attacker to possess a role with permissions to enter HTML tags containing specific data attributes.

Recommendations Update to version 2.1.1.
