The vulnerability CVE-2025-31598 affects WPFactory's Quantity Dynamic Pricing & Bulk Discounts for WooCommerce plugin (versions up to 4.0.3). It is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, user interaction, and scope change.

Successful exploitation of this stored XSS vulnerability can lead to execution of arbitrary scripts in the context of affected users, potentially allowing attackers to steal sensitive information, manipulate content, or perform actions on behalf of the user. The CVSS vector indicates impacts on confidentiality, integrity, and availability, but the overall severity is medium. 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 released, users should consider restricting plugin usage to trusted users only and apply standard web application protections such as Content Security Policy (CSP) to mitigate the risk of script injection. Monitor WPFactory communications for updates and apply patches promptly once available.
