This vulnerability in Marquee Addons for Elementor arises from improper neutralization of input during web page generation, enabling DOM-based cross-site scripting (XSS). The issue affects versions up to 3.8.2 and allows an attacker with low privileges and requiring user interaction to execute script code 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 impacts on confidentiality, integrity, and availability.

Successful exploitation can result in partial compromise of confidentiality, integrity, and availability of the affected web application. This may allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to session hijacking, defacement, or other malicious actions within the scope of the vulnerable component.
