This vulnerability in QantumThemes Kentha (<= 4.7.2) involves improper neutralization of input during web page generation, resulting in a reflected cross-site scripting (XSS) flaw. An attacker can craft a malicious link that, when visited by a user, executes arbitrary scripts in the user's browser session. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope change, and low impact on confidentiality, integrity, and availability.

Successful exploitation can allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability at a low level. The scope is changed, indicating the vulnerability affects resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
