CVE-2026-57380Network attack vector

DOM-based XSS via targetmarker shortcode

Published Jul 13, 2026 · Updated Jul 13, 2026

DOM-based XSS in hupe13 Extensions for Leaflet Map 5.1 and earlier allows remote attackers to execute script via targetmarker. The version 5.2 changelog identifies the targetmarker shortcode as the affected locus, but public records do not disclose which untrusted value reaches which DOM sink without neutralization. Exploitation is unauthenticated but requires a user to interact with crafted content, and executed script runs in the affected site's browser context.
