CVE-2024-44026 is a stored Cross-site Scripting (XSS) vulnerability identified in the Charity Addon for Elementor 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 embedded and persistently stored within the affected website's content. When a victim accesses a compromised page, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, unauthorized actions on behalf of the user, or distribution of malware. The affected versions include all releases up to and including version 1.3.0. The vulnerability does not require authentication or user interaction beyond visiting the infected page, increasing its risk profile. Although no public exploits have been reported yet, the widespread use of Elementor and its addons in WordPress sites globally makes this a critical concern. The vulnerability was publicly disclosed on October 6, 2024, with no CVSS score assigned yet. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is saved on the server and served to multiple users, amplifying the attack impact. The lack of proper input sanitization or output encoding in the plugin's codebase is the root cause, highlighting a need for secure coding practices in third-party WordPress addons.

The impact of CVE-2024-44026 is significant for organizations running WordPress sites with the Charity Addon for Elementor plugin. Successful exploitation can compromise the confidentiality and integrity of user data by enabling attackers to steal cookies, session tokens, or other sensitive information. It can also lead to unauthorized actions performed on behalf of users, including administrative functions if an administrator visits the infected page. Additionally, attackers can use the vulnerability to distribute malware or redirect users to malicious sites, damaging organizational reputation and user trust. The persistent nature of stored XSS means multiple users can be affected over time, increasing the potential damage. For organizations handling sensitive donor or charity-related information, the risk is amplified. Moreover, exploitation requires no authentication, making it accessible to remote attackers without credentials. The vulnerability could also be leveraged as a foothold for further attacks within the network or to escalate privileges. Given the extensive use of Elementor and its addons worldwide, the scope of affected systems is broad, potentially impacting thousands of websites.

To mitigate CVE-2024-44026, organizations should immediately update the Charity Addon for Elementor plugin to a patched version once released by nicheaddons. Until a patch is available, administrators should consider disabling or removing the vulnerable addon to eliminate the attack surface. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads can provide temporary protection. Site owners should audit and sanitize all user-generated content inputs rigorously, applying strict input validation and output encoding to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on the website. Regularly scan the website for malicious scripts or injected content using security plugins or external services. Educate site administrators and content editors about the risks of XSS and safe content handling practices. Finally, monitor security advisories from nicheaddons and WordPress security communities for updates and further recommendations.
