GHSA-4h7g-5542-v3fc: mediawiki/maps has stored XSS through the overlays parameter in the display_map parser functionCVE-2026-52854 0 A stored cross-site scripting (XSS) vulnerability exists in the mediawiki/maps extension through the overlays parameter of the display_map parser function when using the leaflet service.
