CVE-2025-64292 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the PascalBajorat Analytics Germanized for Google Analytics plugin, specifically versions up to 1.6.2. This vulnerability stems from improper neutralization of input during the generation of web pages, allowing malicious scripts to be injected into the Document Object Model (DOM) of affected web pages. Unlike reflected or stored XSS, DOM-based XSS occurs entirely on the client side, where the injected script manipulates the DOM environment in the victim’s browser. The vulnerability does not require authentication but does require user interaction, such as clicking a crafted link or visiting a malicious webpage that triggers the script injection. The CVSS score of 5.4 (medium severity) reflects that the attack vector is network-based with low attack complexity and no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity, potentially allowing attackers to steal session cookies, perform actions on behalf of users, or manipulate displayed content. Availability is not impacted. No known exploits have been reported in the wild, suggesting limited active exploitation at this time. The vulnerability affects websites using this plugin, which is popular among German-speaking and European WordPress users for integrating Google Analytics with enhanced privacy and localization features. The lack of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for vigilance and interim mitigations.

For European organizations, especially those operating websites with the PascalBajorat Analytics Germanized for Google Analytics plugin, this vulnerability poses risks including session hijacking, theft of sensitive user data, and unauthorized actions performed in the context of authenticated users. The impact is particularly relevant for e-commerce, financial services, and any sector relying on web applications for customer interaction. Given the plugin’s focus on Germanized analytics, organizations in Germany and neighboring countries with strong adoption of localized WordPress plugins are at higher risk. The vulnerability could undermine user trust and lead to regulatory scrutiny under GDPR if personal data is compromised. Although availability is not affected, the integrity and confidentiality breaches could result in reputational damage and financial loss. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers could develop exploits once details become widely known.

1. Monitor official vendor channels and security advisories for patches addressing CVE-2025-64292 and apply updates immediately upon release. 2. Implement strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of DOM-based XSS. 3. Conduct thorough input validation and sanitization on client-side scripts to prevent malicious input from influencing DOM generation. 4. Employ web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting this plugin. 5. Educate users and administrators about the risks of clicking untrusted links and the importance of maintaining updated software. 6. Review and limit the use of third-party plugins to those with active maintenance and security support. 7. Perform regular security assessments and penetration testing focusing on client-side vulnerabilities in web applications.
