The MC Woocommerce Wishlist plugin by Moreconvert Team suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers to craft malicious URLs or inputs that, when processed by the plugin, result in script execution in users' browsers. The issue affects all versions up to 1.9.1. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability. No patch or official fix has been documented in the provided data.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, defacement, or other malicious actions affecting confidentiality, integrity, and availability of user data. The reflected nature means the attack requires user interaction, such as clicking a crafted link. There are no known exploits in the wild at this time.

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 to detect and block reflected XSS attempts. Monitor official Moreconvert Team communications for updates and apply patches promptly once released.
