CVE-2025-63068 identifies a Cross-Site Scripting (XSS) vulnerability in the sevenspark Contact Form 7 Dynamic Text Extension plugin for WordPress, specifically in versions up to 5.0.3. The vulnerability stems from improper neutralization of script-related HTML tags within dynamic text fields, allowing attackers to inject malicious JavaScript code into web pages rendered by the plugin. This code injection can be executed remotely without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The injected scripts could be used to steal cookies, session tokens, or other sensitive information from users visiting affected sites, thereby compromising confidentiality. However, the vulnerability does not directly impact data integrity or system availability. The plugin is widely used to enhance Contact Form 7 functionality by dynamically populating form fields, making it a common target for attackers seeking to exploit web application weaknesses. Although no known exploits have been reported in the wild, the medium CVSS score of 5.3 reflects moderate risk due to ease of exploitation and potential data exposure. The lack of a patch link suggests that a fix may be pending or users must rely on manual mitigations. The vulnerability was published in December 2025, with the initial reservation in October 2025, indicating recent discovery and disclosure. Organizations using this plugin should prioritize assessment and remediation to prevent exploitation.

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality of user data collected via web forms. Attackers exploiting this XSS flaw can execute arbitrary scripts in the context of the affected website, potentially harvesting sensitive information such as login credentials, personal data, or session cookies. This can lead to unauthorized access or identity theft. While the vulnerability does not directly compromise data integrity or availability, successful exploitation can facilitate further attacks like phishing or session hijacking. Organizations in sectors with strict data protection regulations (e.g., GDPR) face compliance risks if user data is exposed. Additionally, reputational damage and loss of customer trust may result from such incidents. The threat is particularly relevant for businesses relying on WordPress with Contact Form 7 Dynamic Text Extension for customer interactions, including e-commerce, healthcare, and financial services. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. Proactive mitigation is essential to safeguard sensitive information and maintain regulatory compliance.

1. Monitor sevenspark and WordPress plugin repositories for official patches addressing CVE-2025-63068 and apply updates immediately upon release. 2. Until a patch is available, implement strict input validation and sanitization on all user-supplied data processed by the Contact Form 7 Dynamic Text Extension to neutralize script tags and other potentially malicious content. 3. Deploy a robust Content Security Policy (CSP) that restricts the execution of inline scripts and limits sources of executable code to trusted domains. 4. Utilize Web Application Firewalls (WAFs) with custom rules to detect and block common XSS attack patterns targeting this plugin. 5. Conduct regular security audits and penetration testing focused on web forms and dynamic content injection points. 6. Educate web administrators and developers about secure coding practices and the risks associated with dynamic text extensions. 7. Consider temporarily disabling the vulnerable plugin if immediate patching or mitigation is not feasible, especially on high-risk or sensitive websites. 8. Monitor web server and application logs for unusual activities indicative of attempted XSS exploitation.
