CVE-2024-51862 is a stored cross-site scripting vulnerability identified in the Google Visualization Charts library developed by Baptiste Wicht, affecting versions up to and including 0.1. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be injected and stored within the application. When other users access the affected pages, the injected scripts execute in their browsers, potentially compromising their session data, stealing credentials, or performing unauthorized actions on their behalf. This vulnerability is particularly dangerous because it is stored XSS, meaning the malicious payload persists on the server or in the application data, increasing the likelihood of widespread impact. The vulnerability does not require user interaction beyond visiting the affected page, and no authentication is necessary to exploit it, making it easier for attackers to leverage. Although no public exploits have been reported yet, the lack of a patch at the time of publication means that applications using this library remain vulnerable. The affected product is primarily used in web applications to render interactive charts, so any web service or platform integrating this library is at risk. The vulnerability highlights the importance of proper input validation and output encoding in web development to prevent injection attacks. The absence of a CVSS score necessitates an expert severity assessment based on the technical details and potential impact.

The impact of CVE-2024-51862 is significant for organizations that use the Google Visualization Charts library in their web applications. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of the victim's browser, resulting in session hijacking, theft of sensitive information such as cookies or credentials, and unauthorized actions performed with the victim's privileges. This can compromise user accounts, lead to data breaches, and damage organizational reputation. Since the vulnerability is stored XSS, the malicious payload can affect multiple users over time, increasing the attack surface. The ease of exploitation without authentication or user interaction further elevates the risk. Organizations in sectors such as finance, healthcare, e-commerce, and government, where sensitive data is displayed or processed via web interfaces, are particularly vulnerable. Additionally, attackers could use this vulnerability as a foothold for further attacks within the network or to distribute malware. The lack of a patch at the time of disclosure means that affected organizations must act quickly to mitigate risk. Overall, the vulnerability threatens confidentiality, integrity, and potentially availability if exploited to inject disruptive scripts.

To mitigate CVE-2024-51862, organizations should first monitor for and apply any official patches or updates released by the Baptiste Wicht project as soon as they become available. Until a patch is released, developers should implement strict input validation to reject or sanitize any user-supplied data that could be rendered in the charts. Employing context-aware output encoding (e.g., HTML entity encoding) when rendering data in the visualization can prevent script injection. Additionally, implementing Content Security Policy (CSP) headers can help limit the impact of injected scripts by restricting the sources from which scripts can be loaded and executed. Web application firewalls (WAFs) can be configured to detect and block common XSS payloads targeting this vulnerability. Regular security code reviews and penetration testing focused on input handling in chart rendering components are recommended. Finally, educating developers on secure coding practices related to web content generation will help prevent similar vulnerabilities in the future.
