WordPress vulnerability analysis and mitigation

The Professional Contact Form plugin for WordPress has been identified with a Cross-Site Request Forgery (CSRF) vulnerability, tracked as CVE-2025-9944. The vulnerability affects all versions up to and including 1.0.0, and was discovered by Nabil Irawan from Heroes Cyber. The issue was publicly disclosed on September 26, 2025, and was subsequently published in the National Vulnerability Database (NVD) on September 27, 2025 (NVD, Wordfence).

The vulnerability stems from missing or incorrect nonce validation in the watchforcontactformsubmit function within the plugin's mailer component. The security issue has been assigned a CVSS v3.1 Base Score of 4.3 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. This indicates that the vulnerability can be exploited remotely, requires low attack complexity, needs no privileges, but does require user interaction. The weakness has been categorized as CWE-352: Cross-Site Request Forgery (NVD).

The vulnerability allows unauthenticated attackers to trigger test email sending through forged requests, provided they can successfully trick a site administrator into performing specific actions, such as clicking on a malicious link. While the direct impact appears limited to email functionality, this could potentially be used in social engineering attacks or to cause confusion and disruption to the site's communication systems (NVD).

The vulnerability exists in Professional Contact Form plugin versions up to and including 1.0.0. Site administrators are advised to implement proper CSRF protection mechanisms and ensure all form submissions include appropriate nonce validation. The specific fix involves updating the watchforcontactformsubmit function to include proper security checks (WordPress Plugin).
