CVE-2024-50555 is a stored cross-site scripting (XSS) vulnerability identified in the Elementor Website Builder plugin for WordPress, affecting all versions up to and including 3.29.0. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious JavaScript code that is stored persistently on the affected website. When other users or administrators visit the compromised pages, the malicious script executes in their browsers within the context of the vulnerable site. The CVSS v3.1 score of 6.5 reflects a medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges, and user interaction. The scope is changed, meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact includes limited confidentiality, integrity, and availability losses, such as session hijacking, defacement, or redirection to malicious sites. No known public exploits have been reported yet, but the presence of stored XSS in a widely used website builder plugin poses a significant risk due to the potential for widespread exploitation. The vulnerability was published in early 2026, with no official patches linked yet, emphasizing the need for vigilance and interim mitigations.

The impact of CVE-2024-50555 is significant for organizations relying on Elementor for website creation and management. Stored XSS vulnerabilities can lead to session hijacking, theft of sensitive user data, unauthorized actions performed on behalf of users, website defacement, and distribution of malware. Since Elementor is a popular WordPress plugin used by millions of websites globally, exploitation could affect a broad range of sectors including e-commerce, media, education, and government. Attackers could leverage this vulnerability to compromise user accounts, inject phishing content, or disrupt website availability. The requirement for low privileges and user interaction lowers the barrier for exploitation, increasing risk. Additionally, the scope change means that the impact could extend beyond the immediate plugin, potentially affecting other integrated components or user data. Organizations may face reputational damage, regulatory penalties, and operational disruptions if exploited.

To mitigate CVE-2024-50555, organizations should immediately monitor for updates from Elementor and apply patches as soon as they become available. Until official patches are released, administrators should restrict plugin access to trusted users only and limit privileges to the minimum necessary. Implementing robust input validation and sanitization on all user inputs related to Elementor content can reduce injection risks. Deploying Content Security Policy (CSP) headers can help prevent execution of unauthorized scripts. Regularly scanning websites for XSS vulnerabilities using automated tools and manual testing is recommended. Additionally, educating site administrators and users about the risks of clicking on suspicious links or interacting with untrusted content can reduce exploitation likelihood. Backup website data frequently to enable quick recovery in case of compromise. Finally, consider using web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting Elementor.
