This vulnerability in Gavin Affiliate Tools Việt Nam (versions <= 0.3.17) involves improper neutralization of input during web page generation, resulting in reflected cross-site scripting (XSS). An attacker could exploit this to execute arbitrary scripts in the context of a victim's browser, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of malicious scripts in users' browsers, which may result in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The CVSS score of 7.1 reflects a high severity vulnerability with potential significant impact if exploited.

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