CVE-2024-4432 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, found in the Piotnet Addons For Elementor plugin for WordPress. This plugin, widely used to enhance Elementor page builder functionality, suffers from improper neutralization of user-supplied input during web page generation. Specifically, all versions up to and including 2.4.26 fail to adequately sanitize and escape attributes supplied by authenticated users with contributor-level permissions or higher. This flaw allows these users to inject arbitrary JavaScript code into widget attributes that are stored and later rendered on pages viewed by other users. Because the malicious script is stored, it executes automatically when any user accesses the infected page, potentially compromising user sessions, stealing cookies, or performing unauthorized actions on behalf of users. The vulnerability requires no user interaction beyond visiting the affected page but does require the attacker to have authenticated access with contributor or higher privileges, which is a moderate barrier but common in multi-user WordPress environments. The CVSS v3.1 score is 6.4, reflecting medium severity with network attack vector, low attack complexity, and privileges required. No official patches or exploit code are currently publicly available, but the risk remains significant due to the widespread use of the plugin and WordPress itself. Mitigation involves restricting contributor permissions, sanitizing inputs, or applying updates once available.

The impact of CVE-2024-4432 is primarily on the confidentiality and integrity of affected WordPress sites. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the victim's browser, which can lead to session hijacking, theft of sensitive information such as cookies or credentials, defacement of websites, or redirection to malicious sites. This can damage organizational reputation, lead to data breaches, and facilitate further attacks such as phishing or malware distribution. Since the vulnerability requires contributor-level access, insider threats or compromised contributor accounts pose a significant risk. The scope includes any WordPress site using the vulnerable Piotnet Addons For Elementor plugin, which is popular among web developers and agencies. The lack of user interaction needed for exploitation increases risk, as any visitor to the infected page can be affected. Although no known exploits are reported in the wild yet, the medium severity and ease of exploitation by authenticated users make this a notable threat for organizations relying on this plugin for website functionality.

Organizations should immediately audit user roles and permissions, limiting contributor-level access to trusted individuals only. Until an official patch is released, consider disabling or removing the Piotnet Addons For Elementor plugin if feasible. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious script injections targeting widget attributes. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly monitor website content for unauthorized changes or injected scripts. Educate contributors about safe input practices and the risks of injecting untrusted content. Once a patch is available, prioritize timely updates of the plugin. Additionally, consider using security plugins that sanitize inputs or provide enhanced XSS protection for WordPress environments. Conduct penetration testing focused on XSS vulnerabilities in multi-user environments to identify similar risks.
