CVE-2025-30631 is a reflected Cross-site Scripting (XSS) vulnerability classified under CWE-79 that affects two WordPress plugins developed by AA-Team: the Woocommerce Sales Funnel Builder (up to version 1.1) and the Amazon Affiliates Addon for WPBakery Page Builder (up to version 1.2). The vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious JavaScript code into web pages viewed by other users. This reflected XSS does not require authentication privileges but does require user interaction, typically by tricking a victim into clicking a crafted URL containing malicious payloads. The CVSS v3.1 score of 7.1 indicates a high severity, with an attack vector over the network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), and scope changed (S:C). The impact includes partial loss of confidentiality, integrity, and availability, as the attacker can execute arbitrary scripts in the context of the victim’s browser session, potentially leading to session hijacking, credential theft, defacement, or redirection to malicious sites. The vulnerability affects e-commerce and affiliate marketing sites using these plugins, which are popular in WordPress environments. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly to prevent exploitation.

For European organizations, this vulnerability poses significant risks, especially for those operating e-commerce platforms or affiliate marketing websites using WooCommerce and WPBakery Page Builder plugins. Exploitation could lead to theft of user credentials, session hijacking, unauthorized transactions, and reputational damage. The reflected XSS can also be used to deliver further malware or phishing attacks targeting customers or employees. Given the widespread use of WooCommerce in Europe, particularly in countries with mature e-commerce markets, the potential impact includes financial losses, regulatory penalties under GDPR for data breaches, and erosion of customer trust. The vulnerability’s ability to affect confidentiality, integrity, and availability makes it a critical concern for business continuity and data protection compliance within the European Union and neighboring countries.

1. Immediate implementation of input validation and output encoding on all user-supplied data within the affected plugins to neutralize malicious scripts. 2. Disable or remove the affected plugins if they are not essential to business operations until patches are available. 3. Monitor web server logs and web application firewall (WAF) alerts for suspicious requests containing script payloads or unusual URL parameters targeting these plugins. 4. Educate users and administrators about the risks of clicking unknown or suspicious links that could trigger reflected XSS attacks. 5. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. 6. Regularly update WordPress core, themes, and plugins to the latest versions once patches are released by AA-Team. 7. Conduct thorough security assessments and penetration testing focusing on input handling in web applications using these plugins. 8. Use multi-factor authentication (MFA) to reduce the impact of credential theft resulting from XSS exploitation.
