This vulnerability involves improper neutralization of input in the Aman Popup addon for Ninja Forms, leading to DOM-based cross-site scripting (XSS). The issue affects versions up to 3.4 and allows an attacker with low privileges and requiring user interaction to execute malicious scripts in the context of the affected web page. The CVSS 3.1 base score is 6.5, reflecting medium severity with network attack vector, low attack complexity, and partial impact on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in the victim's browser, potentially allowing data theft, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of the affected system. The vulnerability requires user interaction and low privileges, limiting the ease of exploitation.
