This vulnerability in the WPFactory Coupons & Add to Cart by URL Links for WooCommerce plugin allows stored cross-site scripting due to improper input neutralization during web page generation. It affects all versions up to 1.7.7. An attacker with low privileges can inject malicious scripts that execute when a user interacts with the affected page, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required are low, user interaction is required, and the scope is changed.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website, potentially allowing attackers to steal user data, manipulate site content, or disrupt availability. The impact is rated medium with partial loss of confidentiality, integrity, and availability. There are no reports of active exploitation in the wild.

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 features to trusted users only and monitor for suspicious activity related to input handling. Avoid exposing the affected plugin functionality to untrusted users. Follow vendor channels for updates on patches or official mitigations.
