The redqteam Wishlist plugin versions up to 2.1.0 contain a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows attackers to inject and execute arbitrary scripts in users' browsers when they interact with crafted URLs or inputs that the plugin reflects without proper sanitization. The vulnerability has a CVSS 3.1 score of 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 official fix information is provided, and the product is not a cloud service, so remediation depends on vendor updates.

Successful exploitation of this vulnerability could 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 of the affected system or user data. The reflected nature of the XSS requires user interaction to trigger the attack. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when interacting with untrusted inputs or URLs related to the Wishlist plugin. Implementing web application firewall (WAF) rules to detect and block reflected XSS attempts may provide temporary mitigation. Monitor vendor channels for updates or patches addressing this vulnerability.
