CVE-2025-28902 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Benjamin Pick Contact Form 7 Select Box Editor Button WordPress plugin, affecting versions up to and including 0.6. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting unauthorized requests to a web application, exploiting the user's active session and privileges. In this case, the vulnerability allows an attacker to perform actions on the plugin's functionality without the user's consent, potentially modifying form settings or other plugin configurations. The vulnerability arises due to missing or inadequate anti-CSRF tokens or nonce verification in the plugin's request handling. Since the plugin operates within the WordPress admin environment, exploitation requires the victim to be logged in with sufficient privileges, typically an administrator or editor role. No public exploits have been reported yet, but the vulnerability is publicly disclosed and published in the CVE database. The absence of a CVSS score means severity must be inferred from the nature of CSRF attacks, which can lead to unauthorized changes, data integrity issues, or site misconfigurations. The plugin is used by WordPress sites that rely on Contact Form 7 for form management, making the attack surface limited to those installations. The vulnerability was reserved and published in March 2025 by Patchstack. No patches or mitigation links are currently provided, indicating that users must monitor for updates or apply manual mitigations.

The impact of this CSRF vulnerability can be significant for organizations using the affected plugin. An attacker could exploit the vulnerability to alter form configurations, potentially redirecting form submissions, injecting malicious content, or disrupting form functionality. This could lead to data integrity issues, loss of user trust, or exposure of sensitive information collected via forms. Since the vulnerability requires an authenticated user session, the risk is primarily to sites with multiple administrators or editors who might be targeted via social engineering or phishing to visit malicious sites. The availability of the website or form functionality could also be impaired if attackers modify or disable forms. For organizations relying on Contact Form 7 for critical user interactions, such as customer inquiries or lead generation, this could disrupt business operations. While no known exploits are currently active, the public disclosure increases the risk of exploitation attempts. The scope is limited to WordPress sites using this specific plugin, but given WordPress's large market share, the absolute number of affected sites could be substantial. The vulnerability does not directly expose confidential data but can indirectly compromise data integrity and availability.

To mitigate this vulnerability, organizations should first check for official patches or updates from the plugin vendor and apply them promptly once available. In the absence of patches, administrators should restrict access to the WordPress admin area to trusted users only and implement multi-factor authentication to reduce the risk of session hijacking. Employing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide additional protection. Site owners can also implement custom nonce verification for plugin actions or disable the vulnerable plugin if it is not essential. Regularly auditing user roles and permissions to minimize the number of users with administrative privileges reduces the attack surface. Educating users about phishing and social engineering risks can prevent attackers from leveraging authenticated sessions. Monitoring logs for unusual administrative actions may help detect exploitation attempts early. Finally, isolating the WordPress environment and ensuring secure session management practices will help mitigate CSRF risks.
