This vulnerability in AcuGIS Leaflet Maps (up to version 5.1.1.0) allows reflected Cross-site Scripting due to improper input neutralization during web page generation. An attacker can craft a malicious URL or input that, when processed by the application, results in script execution in the user's browser. The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data. However, no known exploits have been reported in the wild.
