CVE-2024-49264 is a Stored Cross-site Scripting (XSS) vulnerability identified in the Events Addon for Elementor, a plugin developed by nicheaddons. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently within the affected website's content. When other users or administrators view the compromised content, the malicious JavaScript executes in their browsers, potentially leading to session hijacking, theft of cookies or credentials, defacement of the website, or redirection to malicious domains. The vulnerability affects all versions of the Events Addon for Elementor up to and including version 2.2.0. No CVSS score has been assigned yet, and no official patches or exploit code have been published at the time of disclosure. The plugin is widely used in WordPress environments that utilize Elementor for event management, making the attack surface significant. The vulnerability does not require user interaction beyond visiting a compromised page and does not require authentication to exploit if the attacker can submit malicious input. This type of Stored XSS is particularly dangerous because the payload persists and can affect multiple users over time. The lack of immediate patches necessitates that organizations implement interim mitigations such as input sanitization and output encoding at the application level or disabling the vulnerable plugin until fixed.

The impact of CVE-2024-49264 can be substantial for organizations using the Events Addon for Elementor. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of users’ browsers, which can lead to session hijacking, unauthorized actions on behalf of users, theft of sensitive information such as cookies or credentials, and potential website defacement or redirection to phishing or malware sites. This compromises the confidentiality and integrity of user data and can damage organizational reputation. For websites managing event registrations or sensitive user interactions, the risk is amplified. Additionally, the persistent nature of Stored XSS means that once injected, the malicious script can affect many users over time until removed. The absence of a patch increases the window of exposure. Organizations with high traffic event sites or those handling sensitive user data are particularly vulnerable. The vulnerability could also be leveraged as a foothold for further attacks within a network if administrative users are compromised.

1. Immediately audit and sanitize all user inputs related to event creation or editing within the Events Addon for Elementor to prevent injection of malicious scripts. 2. Implement strict output encoding on all data rendered on event pages to neutralize any injected scripts. 3. Temporarily disable or remove the Events Addon for Elementor plugin if feasible until an official patch is released. 4. Monitor web server and application logs for unusual input patterns or suspicious activity indicative of attempted XSS exploitation. 5. Educate site administrators and users about the risks of clicking on suspicious links or interacting with untrusted content. 6. Use Web Application Firewalls (WAFs) with rules designed to detect and block XSS payloads targeting this plugin. 7. Keep WordPress core, Elementor, and all plugins updated regularly and subscribe to vendor security advisories for timely patching. 8. Consider implementing Content Security Policy (CSP) headers to restrict execution of unauthorized scripts on affected sites. 9. Conduct regular security assessments and penetration tests focusing on input validation and output encoding controls within the event management workflows.
