Project: GLightbox [1] Date: 2025-June-25 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: <1.0.16 CVE IDs: CVE-2025-48922 Description:  GLightbox module is a pure Javascript lightbox for CKEditor.

The module doesn't sufficiently filter user-supplied text for the GLightbox Javascript library leading to a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the permissions to edit content that is configured to support the Glightbox module.

Solution:  Install the latest version:

* If you use the GLightbox module, upgrade to GLightbox 1.0.16 [3]
