A vulnerability has been identified in Element maps-ng V47 (All versions < V47.12.3), Element maps-ng V48 (All versions < V48.11.3), Element maps-ng V49 (All versions < V49.16.1). The si-map component does not properly neutralize user-controllable input of the points property that is used to render the tooltip label of map pins.
