The thanhtungtnt Video List Manager up to version 1.7 suffers from a Stored Cross-site Scripting (XSS) vulnerability due to improper input neutralization during web page generation. This flaw allows attackers to inject malicious scripts that persist on the affected application, potentially impacting users who access the compromised content. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and the product is not a cloud service.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to data theft, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability of the application and its users. However, no known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules or input sanitization as temporary mitigations.
