CVE-2024-54210 is a stored cross-site scripting (XSS) vulnerability identified in the codexshaper Advanced Element Bucket Addons for Elementor plugin, specifically affecting versions up to and including 1.0.2. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be stored persistently within the plugin's data fields. When a victim visits a compromised page, the injected script executes in their browser context, potentially enabling attackers to steal session cookies, perform actions on behalf of the user, or redirect users to malicious websites. This vulnerability is particularly dangerous because it does not require user interaction beyond visiting a compromised page, and it affects a widely used WordPress plugin that extends the Elementor page builder functionality. Although no public exploits have been reported yet, the nature of stored XSS makes it a high-risk issue since attackers can embed payloads that persist and affect multiple users. The lack of an official patch at the time of publication means that affected sites remain vulnerable until updates are released or alternative mitigations are applied. The vulnerability was assigned by Patchstack and published on December 6, 2024, but no CVSS score has been provided. The plugin's user base includes many websites globally, increasing the potential attack surface.

The impact of CVE-2024-54210 is significant for organizations using the affected plugin on WordPress sites. Successful exploitation can compromise user confidentiality by stealing session tokens or personal data, undermine integrity by allowing unauthorized content injection or defacement, and potentially affect availability if attackers use the vulnerability to deploy disruptive scripts. For organizations, this can lead to reputational damage, loss of user trust, and potential regulatory consequences if sensitive data is exposed. Since the vulnerability is stored XSS, it can affect multiple users visiting the compromised pages, amplifying the scope of impact. Attackers could leverage this vulnerability to conduct phishing campaigns, spread malware, or pivot to further attacks within the network. Given the widespread use of Elementor and its addons, many small to medium businesses, blogs, and e-commerce sites are at risk, making this a broad and impactful threat.

To mitigate CVE-2024-54210, organizations should immediately monitor for any suspicious activity or unusual script injections on their WordPress sites using the affected plugin. Until an official patch is released by codexshaper, consider temporarily disabling the Advanced Element Bucket Addons for Elementor plugin to prevent exploitation. Review and sanitize all user inputs and stored content related to the plugin manually, employing strict input validation and output encoding techniques to neutralize potentially malicious scripts. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly back up website data to enable quick restoration in case of compromise. Once a patch is available, prioritize prompt updating of the plugin to the fixed version. Additionally, educate site administrators and users about the risks of XSS and encourage vigilance against phishing attempts that may leverage this vulnerability.
