CVE-2025-62896 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the digitaldonkey Multilang Contact Form plugin, specifically affecting versions up to 1.5. The vulnerability allows an attacker to craft malicious requests that, when executed by an authenticated user, can cause the plugin to store malicious scripts within the contact form data, leading to Stored Cross-Site Scripting (XSS). This stored XSS can then execute arbitrary JavaScript in the context of the victim's browser, potentially stealing session cookies, performing actions on behalf of the user, or redirecting users to malicious sites. The absence of CSRF protections such as anti-CSRF tokens in the plugin's request handling enables attackers to exploit this flaw without requiring direct user interaction beyond visiting a crafted webpage. The vulnerability affects the confidentiality and integrity of user data and can disrupt availability if exploited to inject disruptive scripts. No official patch or CVSS score was available at the time of publication, but the vulnerability was publicly disclosed on October 27, 2025. The plugin is commonly used in multilingual WordPress sites to manage contact forms, making it a target for attackers aiming to compromise websites that rely on this plugin for user communication.

For European organizations, this vulnerability poses a significant risk, especially for those operating multilingual websites using the digitaldonkey Multilang Contact Form plugin. Exploitation could lead to unauthorized actions performed on behalf of users, data theft, session hijacking, and defacement or redirection of websites. This can damage organizational reputation, lead to regulatory non-compliance under GDPR due to data breaches, and cause operational disruptions. The stored XSS aspect increases the risk of persistent attacks affecting multiple users over time. Organizations in sectors such as e-commerce, government, and finance, which often use multilingual contact forms to engage with diverse user bases, are particularly vulnerable. The lack of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for remediation given the potential impact.

1. Monitor for official patches or updates from digitaldonkey and apply them promptly once released. 2. Implement web application firewall (WAF) rules to detect and block CSRF attack patterns targeting the contact form endpoints. 3. Enforce strict input validation and sanitization on all form inputs to prevent injection of malicious scripts. 4. Add anti-CSRF tokens to all state-changing requests within the contact form to ensure requests are legitimate. 5. Conduct regular security audits and penetration testing focusing on web forms and user input handling. 6. Educate web administrators and developers about CSRF and XSS risks and secure coding practices. 7. Consider temporarily disabling the plugin or replacing it with a more secure alternative if immediate patching is not feasible. 8. Review user permissions and authentication mechanisms to limit the scope of potential CSRF exploitation.
