    "summary": "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.",
