CVE-2025-48322 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the Statify Widget developed by Finn Dohrn. The vulnerability arises from improper neutralization of input during web page generation, allowing malicious scripts to be stored and subsequently executed in the context of users visiting web pages that incorporate the vulnerable widget. The affected versions include all versions up to 1.4.6, with no specific earliest version identified. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be launched remotely over the network with low attack complexity, requires privileges (PR:L) but only limited user interaction (UI:R), and impacts confidentiality, integrity, and availability to a limited extent. The scope is changed (S:C), meaning the vulnerability affects components beyond the vulnerable widget itself, potentially impacting the broader web application environment. Stored XSS vulnerabilities allow attackers to inject malicious JavaScript code that is permanently stored on the target server (e.g., in databases or logs) and executed when other users access the affected content. This can lead to session hijacking, credential theft, defacement, or distribution of malware. The lack of available patches or mitigations at the time of publication increases the risk for organizations using the Statify Widget. No known exploits are reported in the wild yet, but the presence of a stored XSS in a widely used widget can attract attackers once public disclosure occurs.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on the Statify Widget for web analytics or visitor tracking on their websites. Exploitation could lead to unauthorized access to user sessions, theft of sensitive data such as authentication tokens or personal information, and potential defacement or manipulation of web content. This undermines user trust and can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and financial losses. The scope change indicates that the vulnerability could affect multiple components or users beyond the immediate widget, increasing the potential blast radius. Organizations in sectors with high web traffic or handling sensitive user data (e.g., e-commerce, finance, healthcare) are particularly at risk. Additionally, the requirement for some privilege and user interaction may limit mass exploitation but targeted attacks against privileged users or administrators remain a concern. The absence of known exploits currently provides a window for proactive mitigation before widespread abuse occurs.

1. Immediate mitigation should include disabling or removing the Statify Widget from production environments until a patch or secure update is available. 2. Implement strict input validation and output encoding on all user-supplied data within the widget to neutralize potentially malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the web application context. 4. Conduct thorough code reviews and penetration testing focusing on XSS vectors within the widget and the broader application. 5. Monitor web server logs and user reports for suspicious activity indicative of attempted XSS exploitation. 6. Educate privileged users about the risks and encourage cautious interaction with web content that could trigger the vulnerability. 7. Once a patch is released by Finn Dohrn, prioritize timely deployment and verify the effectiveness of the fix. 8. Consider implementing Web Application Firewalls (WAF) with rules tailored to detect and block XSS payloads targeting the widget. 9. Maintain up-to-date backups and incident response plans to quickly recover from any successful exploitation.
