CVE-2025-64196 identifies a reflected Cross-site Scripting (XSS) vulnerability in the Booster for WooCommerce plugin developed by Pluggabl, affecting versions up to and including 7.2.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious JavaScript code that is reflected back to users. This reflected XSS does not require authentication but does require user interaction, typically by tricking a user into clicking a crafted URL or visiting a malicious page. The vulnerability impacts confidentiality by potentially exposing session tokens or sensitive user data, integrity by enabling unauthorized script execution that can alter displayed content or perform actions on behalf of the user, and availability by possibly causing browser crashes or redirecting users to malicious sites. The CVSS v3.1 base score of 7.1 reflects a high severity, with attack vector being network (remote), low attack complexity, no privileges required, user interaction required, and scope changed due to potential impact beyond the vulnerable component. No known exploits have been reported in the wild as of the publication date. Booster for WooCommerce is a widely used plugin that extends WooCommerce functionality, a popular e-commerce platform for WordPress. Given the plugin’s role in e-commerce environments, exploitation could lead to theft of customer data, session hijacking, or fraudulent transactions. The vulnerability highlights the need for secure input handling and output encoding in web applications, especially in plugins that generate dynamic content based on user input. The absence of an official patch link suggests that users should monitor vendor advisories closely for updates. In the interim, web application firewalls with XSS filtering and strict Content Security Policies (CSP) can help mitigate exploitation risks.

For European organizations, particularly those operating e-commerce websites using WooCommerce with the Booster plugin, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to user sessions, theft of sensitive customer information such as payment details or personal data, and manipulation of website content or transactions. This can result in financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. The reflected XSS nature means attackers can craft malicious URLs that, when clicked by users, execute scripts in their browsers, potentially spreading phishing attacks or malware. The vulnerability’s ability to affect confidentiality, integrity, and availability makes it a critical concern for online retailers and service providers. Additionally, the scope change in the CVSS vector indicates that the impact may extend beyond the immediate plugin, affecting other components or user sessions. Given the widespread use of WooCommerce in Europe, the threat could affect a large number of small to medium-sized enterprises that rely on this plugin for enhanced e-commerce functionality. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors often weaponize publicly disclosed vulnerabilities rapidly.

1. Monitor the vendor’s official channels for a security patch and apply updates to Booster for WooCommerce immediately upon release. 2. Until a patch is available, implement a Web Application Firewall (WAF) with rules specifically designed to detect and block reflected XSS attacks targeting WooCommerce and its plugins. 3. Enforce strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts in browsers. 4. Review and harden input validation and output encoding mechanisms within the WooCommerce environment and any custom code interacting with the Booster plugin. 5. Educate users and administrators about the risks of clicking suspicious links, especially those that could be crafted to exploit reflected XSS vulnerabilities. 6. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including XSS. 7. Consider disabling or limiting the use of vulnerable plugin features that process user input until a patch is applied. 8. Monitor web server and application logs for unusual requests or error patterns indicative of attempted exploitation. 9. Employ multi-factor authentication (MFA) for administrative access to reduce the risk of session hijacking impact. 10. Backup website data regularly to enable quick recovery in case of compromise.
