Project: Lightgallery [1]
Date: 2025-May-21
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: <1.6.0
CVE IDs: CVE-2025-48447
Description: 
This module integrates Drupal with LightGallery, enabling the use of the
LightGallery library with any image field or view.

The module does not adequately sanitize user input in the image field’s
"alt" attribute, potentially allowing cross-site scripting (XSS) attacks when
tags or scripts are inserted.

This vulnerability is partially mitigated by the requirement that an attacker
must have permission to create content containing an image field configured
to use the LightGallery format.

Solution: 
Install the latest version:

  * If you use the Lightgallery module, upgrade to Lightgallery 8.x-1.6 [3]
