CVE-2025-62896 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the digitaldonkey Multilang Contact Form plugin, affecting versions up to and including 1.5. This vulnerability allows attackers to trick authenticated users into submitting malicious requests without their consent, exploiting the absence of proper CSRF protections. The consequence of this CSRF flaw is the ability to inject stored Cross-Site Scripting (XSS) payloads into the contact form, which can then execute arbitrary JavaScript in the context of the victim's browser. The CVSS 3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, with an attack vector over the network, low attack complexity, no privileges required, but requiring user interaction. The vulnerability affects the plugin’s handling of form submissions, lacking anti-CSRF tokens or similar mechanisms to validate request authenticity. Stored XSS can lead to session hijacking, credential theft, or persistent defacement of websites. Although no known exploits are currently in the wild, the public disclosure and high severity score indicate a significant risk. The plugin is commonly used in multilingual WordPress sites to manage contact forms, making it a popular target for attackers aiming to compromise web applications. The lack of official patches at the time of publication necessitates immediate mitigation steps by administrators.

For European organizations, this vulnerability poses a substantial risk to web applications that utilize the digitaldonkey Multilang Contact Form plugin. Exploitation can lead to unauthorized actions performed on behalf of users, including injecting malicious scripts that compromise user sessions and data confidentiality. This can result in data breaches, defacement of corporate websites, loss of customer trust, and potential regulatory penalties under GDPR due to compromised personal data. The stored XSS aspect enables persistent attacks that can affect all visitors to the compromised site, amplifying the damage. Organizations relying on multilingual contact forms for customer interaction or lead generation may experience service disruption and reputational damage. The ease of exploitation without requiring authentication increases the threat surface, especially for public-facing websites. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within the organization’s infrastructure.

To mitigate CVE-2025-62896, organizations should immediately audit their use of the digitaldonkey Multilang Contact Form plugin and identify affected versions (<=1.5). In the absence of an official patch, administrators should implement the following measures: 1) Apply Web Application Firewall (WAF) rules to detect and block CSRF and XSS attack patterns targeting the contact form endpoints. 2) Enforce strict Content Security Policy (CSP) headers to limit the impact of potential XSS payloads. 3) Restrict form submissions to trusted origins by validating the HTTP Referer and Origin headers. 4) Implement manual CSRF tokens or nonce mechanisms if possible by customizing the plugin or using alternative contact form solutions with built-in CSRF protections. 5) Conduct regular security scans and penetration tests focused on web forms and input validation. 6) Educate users about phishing and social engineering tactics that may facilitate CSRF exploitation. 7) Monitor logs for unusual form submission patterns indicative of automated attacks. Once an official patch is released, prioritize immediate deployment. Additionally, consider isolating or disabling the vulnerable plugin if it is not critical to operations.
