CVE-2024-11934 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Formaloo Form Maker & Customer Analytics plugin for WordPress and WooCommerce, affecting all versions up to and including 2.1.3.2. The vulnerability stems from improper neutralization of input during web page generation, specifically through the ‘address’ parameter. Authenticated users with Contributor-level or higher privileges can inject arbitrary JavaScript code into the plugin's form fields. Because the plugin fails to adequately sanitize and escape this input before rendering it on pages, the malicious scripts persist and execute whenever any user accesses the compromised page. This persistent XSS can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of users viewing the infected content. The vulnerability requires authentication but no user interaction beyond viewing the page. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability. No public exploits have been reported yet, but the vulnerability poses a significant risk in environments where multiple users have editing privileges. The plugin is widely used in WordPress and WooCommerce environments for form creation and customer analytics, making the vulnerability relevant for many e-commerce and content management sites.

The primary impact of CVE-2024-11934 is on the confidentiality and integrity of user data within affected WordPress and WooCommerce sites using the Formaloo plugin. Attackers with Contributor-level access can inject malicious scripts that execute in the context of other users’ browsers, potentially stealing session cookies, credentials, or performing unauthorized actions such as privilege escalation or data manipulation. This can lead to account takeover, data leakage, and erosion of user trust. Although the vulnerability does not directly impact availability, successful exploitation can facilitate further attacks that degrade service or compromise site integrity. Organizations relying on this plugin for customer analytics and form management face risks of reputational damage, regulatory non-compliance (if user data is exposed), and operational disruption. The requirement for authenticated access limits the attack surface but does not eliminate risk, especially in environments with multiple contributors or editors. The absence of known exploits in the wild suggests a window for proactive mitigation before widespread abuse occurs.

To mitigate CVE-2024-11934, organizations should immediately update the Formaloo Form Maker & Customer Analytics plugin to a version that addresses this vulnerability once available. In the absence of an official patch, administrators should restrict Contributor-level and higher privileges to trusted users only, minimizing the risk of malicious input injection. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads targeting the ‘address’ parameter can provide temporary protection. Additionally, site owners should enforce Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. Regularly auditing user roles and permissions, combined with monitoring logs for suspicious activity related to form submissions, can help detect exploitation attempts. Developers maintaining custom integrations should ensure proper input validation and output encoding consistent with OWASP guidelines. Finally, educating users about the risks of XSS and maintaining a robust incident response plan will improve resilience against potential attacks.
