    DRUPAL-CONTRIB-2026-204

    Published: 7 Oct 2026Last Modified: 7 Oct 2026

    Summary:

    Details: The Leaflet module provides integration with the Leaflet JS mapping library. Under certain circumstances, when the Leaflet field formatter builds a map it does not filter content titles, leading to a stored cross-site scripting vulnerability. This vulnerability is mitigated by the fact an attacker needs to have permission to create or edit content that is used in a Leaflet map.
