CVE-2024-47298 identifies a stored cross-site scripting vulnerability in the Bold Page Builder plugin developed by boldthemes, affecting all versions up to 5.1.1. Stored XSS occurs when malicious input is improperly sanitized and then permanently stored by the application, later executed in the browsers of users who visit the affected pages. This vulnerability stems from improper neutralization of input during the web page generation process, allowing attackers to inject arbitrary JavaScript code into the content managed by the plugin. When other users or administrators access the compromised page, the injected script executes in their browsers within the context of the vulnerable website, potentially leading to session hijacking, credential theft, defacement, or distribution of malware. The vulnerability does not require authentication or user interaction beyond visiting the infected page, increasing its exploitation potential. Although no public exploits have been reported yet, the widespread use of WordPress and its plugins, including Bold Page Builder, makes this a significant concern. The lack of a CVSS score indicates the need for a manual severity assessment, which is high given the stored nature of the XSS and its impact on confidentiality, integrity, and availability of affected sites.

The stored XSS vulnerability in Bold Page Builder can have severe consequences for organizations running affected versions of the plugin. Attackers can inject persistent malicious scripts that execute in the browsers of site visitors and administrators, leading to theft of sensitive information such as authentication tokens, cookies, and personal data. This can result in account takeover, unauthorized actions on behalf of users, and further compromise of the website or connected systems. Additionally, attackers may deface websites, damage brand reputation, or use the site as a vector to distribute malware to visitors. The vulnerability undermines user trust and can lead to regulatory and compliance issues, especially for organizations handling sensitive or personal data. Given the ease of exploitation and the potential for widespread impact, organizations worldwide using this plugin face significant risk until the vulnerability is remediated.

Organizations should immediately update the Bold Page Builder plugin to a version that addresses this vulnerability once available. Until a patch is released, administrators should implement strict input validation and output encoding on all user-supplied content managed by the plugin. Employing a Web Application Firewall (WAF) with rules designed to detect and block XSS payloads can provide temporary protection. Regularly audit and sanitize existing content to remove any malicious scripts that may have been injected. Limit administrative access to trusted users and enforce multi-factor authentication to reduce the risk of account compromise. Monitor web server and application logs for suspicious activity indicative of exploitation attempts. Additionally, educate site administrators and users about the risks of XSS and safe browsing practices. Coordinating with the plugin vendor for timely updates and security advisories is critical.
