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 input during the generation of web pages, which allows an attacker to inject malicious JavaScript code that is stored persistently within the website's content. When other users or administrators visit the affected pages, the malicious script executes in their browsers within the context of the vulnerable site. This can lead to a range of attacks including session hijacking, credential theft, unauthorized actions on behalf of users, website defacement, or distribution of malware. The vulnerability does not require the attacker to have any authentication privileges, nor does it require user interaction beyond visiting a compromised page, making it easier to exploit. Despite the absence of known exploits in the wild at the time of publication, the widespread deployment of Elementor as a popular WordPress page builder increases the potential attack surface significantly. The lack of a CVSS score indicates that the vulnerability is newly disclosed, but the technical details and nature of stored XSS vulnerabilities suggest a high risk. No official patches or mitigation links were provided in the source data, emphasizing the need for users to monitor vendor updates closely. The vulnerability was reserved in late 2024 and published in early 2026, indicating a recent disclosure timeline.

The impact of CVE-2024-50555 on organizations worldwide can be substantial due to the widespread use of the Elementor Website Builder plugin in WordPress sites, including corporate, governmental, and e-commerce platforms. Successful exploitation can compromise the confidentiality of user data by stealing cookies, session tokens, or other sensitive information. It can also affect integrity by allowing attackers to inject unauthorized content or scripts, potentially defacing websites or redirecting users to malicious domains. Availability impacts may arise indirectly if attackers deploy malware or ransomware through the compromised site. The vulnerability's ease of exploitation without authentication and without requiring user interaction increases the risk of automated or large-scale attacks. Organizations relying on Elementor for their web presence may face reputational damage, regulatory penalties, and operational disruptions if exploited. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within an organization's network or supply chain. The absence of known exploits currently provides a window for proactive mitigation, but the risk remains high given the nature of stored XSS and the plugin's popularity.

1. Immediate mitigation involves updating the Elementor Website Builder plugin to the latest version once a patch addressing CVE-2024-50555 is released by the vendor. Users should monitor official Elementor channels and trusted security advisories for patch announcements. 2. Until a patch is available, implement Web Application Firewall (WAF) rules specifically designed to detect and block malicious script injections targeting Elementor input fields. 3. Conduct a thorough audit of all user-generated content and input fields within Elementor-managed pages to identify and remove any suspicious or malicious scripts. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on the website, limiting the impact of potential XSS payloads. 5. Limit user permissions within WordPress to reduce the risk of unauthorized content injection, ensuring only trusted users can add or edit page content. 6. Regularly back up website data and configurations to enable rapid recovery in case of compromise. 7. Educate site administrators and content editors about the risks of XSS and safe content management practices. 8. Monitor website traffic and logs for unusual activity that may indicate exploitation attempts. These steps, combined with prompt patching, will significantly reduce the risk posed by this vulnerability.
