This vulnerability in Narnoo Commerce Manager (<= 1.6.0) is caused by improper neutralization of input during web page generation, resulting in a reflected cross-site scripting (XSS) issue. An attacker can craft a malicious URL 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 needed, scope changed, and impacts to confidentiality, integrity, and availability. No patch or official remediation guidance is currently available from the vendor.

Successful exploitation of this reflected XSS vulnerability can lead to unauthorized script execution in the context of the victim's browser, potentially allowing theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The vulnerability requires user interaction (clicking a crafted link) and does not require authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with untrusted links and consider implementing web application firewalls or input validation controls as temporary mitigations. Monitor official Narnoo channels for updates.
