CVE-2025-68528 identifies a stored Cross-site Scripting (XSS) vulnerability in the WPFactory Free Shipping Bar: Amount Left for Free Shipping for WooCommerce plugin, versions up to and including 2.4.9. This plugin is used to display dynamic shipping promotion messages on WooCommerce-based e-commerce websites. The vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be stored and later executed in the context of other users' browsers. The CVSS 3.1 base score is 5.4 (medium), with an attack vector of network (remote), low attack complexity, requiring low privileges and user interaction, and impacting confidentiality and integrity with no availability impact. The stored XSS can enable attackers to hijack user sessions, steal cookies, deface content, or perform actions on behalf of authenticated users. Although no public exploits are known, the vulnerability poses a risk to e-commerce sites using this plugin, especially where multiple users interact with the affected pages. The vulnerability was published on December 24, 2025, with no patch links currently available, indicating that organizations should monitor vendor updates closely. The issue is particularly relevant for WooCommerce stores in Europe, where e-commerce adoption is high and such plugins are widely used.

For European organizations, this vulnerability can lead to unauthorized disclosure of user session information and potential account compromise, especially for customers and administrators interacting with the affected WooCommerce stores. Attackers exploiting this vulnerability could inject malicious scripts that execute in the browsers of site visitors or administrators, leading to theft of sensitive data such as authentication tokens or personal information. This can damage customer trust, lead to regulatory non-compliance under GDPR due to data breaches, and cause reputational harm. While availability is not directly impacted, the integrity of displayed content and user data confidentiality are at risk. E-commerce businesses relying on this plugin for shipping promotions may face targeted attacks aiming to disrupt customer experience or conduct fraud. The requirement for low privileges and user interaction means that attackers might leverage social engineering or compromised low-level accounts to exploit the vulnerability. Given the widespread use of WooCommerce in Europe, the potential impact is significant for mid to large-sized online retailers.

1. Monitor WPFactory and WooCommerce plugin repositories for official patches addressing CVE-2025-68528 and apply updates immediately upon release. 2. Until patches are available, implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the Free Shipping Bar plugin. 3. Conduct a thorough review of input validation and output encoding practices in the plugin's codebase if custom modifications exist, ensuring all user inputs are properly sanitized and escaped before rendering. 4. Limit user privileges to the minimum necessary, especially for roles that can input data into the Free Shipping Bar plugin, to reduce the attack surface. 5. Educate site administrators and users about the risks of clicking on suspicious links or interacting with untrusted content to mitigate social engineering vectors. 6. Regularly audit logs and monitor for unusual activity or signs of XSS exploitation attempts. 7. Consider temporarily disabling the Free Shipping Bar plugin if immediate patching is not feasible and the risk is deemed unacceptable. 8. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages.
