Primary sources: NVD · CVE.org · FIRST EPSS

The Contact Form by Bit Form: Multi Step Form, Calculation Contact Form, Payment Contact Form & Custom Contact Form builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.17.4 via file uploads due to insufficient directory listing prevention and lack of randomization of file names. This makes it possible for unauthenticated attackers to extract sensitive data including files uploaded via a form. The vulnerability was partially patched in version 2.17.5.
