CVE-2024-13649 identifies a stored cross-site scripting (XSS) vulnerability in the '140+ Widgets | Xpro Addons For Elementor – FREE' WordPress plugin, which is widely used to enhance Elementor page builder functionality. The vulnerability arises from insufficient input sanitization and output escaping in multiple widgets, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary JavaScript code into pages. This malicious code is stored persistently and executed in the context of any user who visits the affected page, including administrators. The attack vector requires authentication but no user interaction beyond viewing the compromised content. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 base score of 6.4 reflects a medium severity rating, with an attack vector of network, low attack complexity, and privileges required at the contributor level. The scope is changed, as the vulnerability can affect other users beyond the attacker. The impact includes potential confidentiality and integrity loss, such as session hijacking, defacement, or unauthorized actions performed on behalf of victims. No official patches have been linked yet, and no known exploits are reported in the wild, but the risk remains significant for sites using this plugin without mitigation.

This vulnerability can have serious consequences for organizations using the affected WordPress plugin. Attackers with contributor-level access can inject persistent malicious scripts that execute in the browsers of any users visiting the infected pages, including administrators. This can lead to session hijacking, theft of sensitive information, unauthorized actions such as content modification or privilege escalation, and potential defacement. The compromise of administrative accounts could further lead to full site takeover. Since WordPress powers a significant portion of websites globally, and Elementor with its addons is popular among site builders, the attack surface is broad. Organizations relying on this plugin for website functionality risk reputational damage, data breaches, and operational disruptions if exploited. The medium CVSS score reflects moderate ease of exploitation and significant impact on confidentiality and integrity, though availability is not affected.

Organizations should immediately audit their WordPress sites for the presence of the '140+ Widgets | Xpro Addons For Elementor – FREE' plugin and verify the version in use. Until an official patch is released, consider temporarily disabling or removing the plugin to eliminate the attack vector. Restrict Contributor-level permissions strictly and review user roles to minimize the number of users who can inject content. Implement web application firewall (WAF) rules to detect and block suspicious script injections targeting widget inputs. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. Monitor site content for unexpected changes or injected scripts. Educate site administrators and content contributors about the risks of XSS and safe content practices. Once a patch is available, apply it promptly. Additionally, conduct regular security scans and penetration tests focusing on plugin vulnerabilities and input validation.
