CVE-2025-64292 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the PascalBajorat Analytics Germanized for Google Analytics plugin, versions up to and including 1.6.2. The vulnerability stems from improper neutralization of input during web page generation, specifically in the client-side code that processes user-controllable data without adequate sanitization or encoding. This flaw enables attackers to inject malicious JavaScript payloads into the victim's browser context when they interact with the affected web pages, potentially leading to theft of sensitive information such as cookies, session tokens, or manipulation of the DOM. The vulnerability is exploitable remotely over the network (AV:N) without requiring authentication (PR:N), but it requires user interaction (UI:R), such as clicking a crafted link or visiting a malicious page. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component and the user's browser session. The CVSS 3.1 base score is 5.4, indicating a medium severity level, with impacts on confidentiality and integrity but no impact on availability. No known exploits have been reported in the wild, and no official patches or updates have been released at the time of publication. The vulnerability affects websites using the Analytics Germanized for Google Analytics plugin, which is popular among WordPress users, especially in German-speaking regions. Attackers could leverage this vulnerability to conduct targeted phishing campaigns, session hijacking, or defacement attacks by injecting malicious scripts that execute in the context of the victim's browser.

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of user data processed through affected websites. Exploitation could lead to theft of session cookies, enabling account takeover or unauthorized access to user accounts. It could also facilitate the injection of malicious content, damaging the organization's reputation and potentially leading to regulatory scrutiny under GDPR if personal data is compromised. Since the vulnerability is client-side and requires user interaction, the risk is somewhat mitigated by user awareness but remains significant for high-traffic websites or those serving sensitive user groups. Organizations relying on Analytics Germanized for Google Analytics for compliance or data analytics may face disruptions if attackers exploit this flaw to manipulate analytics data or inject misleading content. The absence of availability impact means service disruption is unlikely, but the integrity of web content and user trust could be undermined. Overall, the threat could affect customer trust, lead to data breaches, and incur financial and legal consequences, especially in countries with strict data protection laws.

1. Monitor for official patches or updates from PascalBajorat and apply them immediately once available to remediate the vulnerability. 2. Implement strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Sanitize and encode all user-controllable inputs on the client side, ensuring that any data processed by the plugin is properly neutralized before rendering. 4. Conduct regular security audits and penetration testing focusing on client-side vulnerabilities in web applications using this plugin. 5. Educate end-users and administrators about the risks of clicking on suspicious links and the importance of browser security hygiene. 6. Consider temporarily disabling or replacing the Analytics Germanized for Google Analytics plugin with alternative analytics solutions until a secure version is confirmed. 7. Employ web application firewalls (WAF) with rules tuned to detect and block XSS payloads targeting this specific plugin. 8. Review and limit the exposure of sensitive data in client-side scripts and cookies to minimize the impact if exploitation occurs.
