This vulnerability involves improper neutralization of input during web page generation in the Fast Simon Search, Filters & Merchandising for WooCommerce plugin, leading to stored cross-site scripting (XSS). It affects all versions up to 3.0.58. The flaw allows an attacker with low privileges to inject malicious scripts that execute when other users view the affected pages, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and partial impacts on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of affected users, potentially allowing theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The vulnerability requires an attacker to have low privileges and user interaction, limiting the ease of exploitation. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix links are provided, users should monitor Fast Simon's official channels for updates. In the meantime, consider restricting user input or applying web application firewall (WAF) rules to detect and block suspicious payloads related to XSS attacks specific to this plugin.
