What it is

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.

This could allow an attacker to craft a malicious URL that, when loaded by a victim and the map pin is hovered over, executes arbitrary script code within the victim's browser session.
