# Drupal Leaflet module: stored cross-site scripting through unsanitized input

The Leaflet module for Drupal, which renders interactive maps, has a stored cross-site scripting flaw in versions up to and including 10.4.13. An attacker who can save crafted content can run JavaScript in the browser of other users who view the page.

## How to check

- Check the installed Leaflet module version in the Drupal admin under Extend, or with `drush pm:list --filter=leaflet`
- Confirm whether the site uses the Leaflet module at all
