This vulnerability involves improper input sanitization in the WPFactory Sitewide Discount for WooCommerce plugin, leading to stored cross-site scripting (XSS). An attacker with low privileges can inject malicious scripts that execute when other users view affected pages. The vulnerability affects all versions up to 2.2.1. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope changed, with partial impacts on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected site, potentially leading to data disclosure, modification, or disruption of service. The medium severity reflects these partial impacts on confidentiality, integrity, and availability. However, exploitation requires user interaction and low privileges, limiting the attacker's initial access level.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the plugin's input interfaces and monitor for suspicious activity related to stored XSS. Avoid granting unnecessary privileges to users who can input data into the plugin. Follow vendor communications for updates on patches or official mitigations.
