The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to unauthorized Malichimp API key update due to an insufficient capability check on the verifyRequest function in all versions up to, and including, 5.1.18.

At the same time, missing Mailchimp API key validation allows the redirect of the integration requests to the attacker-controlled server.
AI Analysis
Technical Summary
The Fluent Forms plugin for WordPress, used for creating customizable contact forms, surveys, quizzes, and conversational forms, contains an improper authorization vulnerability (CWE-285) in all versions up to 5.1.18. The verifyRequest function does not adequately check user capabilities, allowing users with Subscriber-level access or above to modify the Mailchimp API key used for integration. Furthermore, the plugin does not validate the Mailchimp API key, which can be exploited to redirect integration requests to attacker-controlled servers. The vulnerability has a CVSS 3.1 base score of 4.2, indicating medium severity, with network attack vector, high attack complexity, low privileges required, no user interaction, and impacts on confidentiality and integrity.
Potential Impact
An attacker with Subscriber-level access or higher can update the Mailchimp API key used by the plugin, potentially redirecting integration requests to malicious servers. This could lead to unauthorized data interception or manipulation of Mailchimp-related communications. The confidentiality and integrity of data exchanged via the Mailchimp integration are impacted, but availability is not affected. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict user roles to trusted individuals only and monitor for unauthorized changes to Mailchimp API keys. Avoid granting Subscriber-level or higher access to untrusted users. Review plugin updates regularly and apply any official patches once released.
