Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.13.4. This is due to missing or incorrect nonce validation on the listen_for_saving_export_schedule() function. This makes it possible for unauthenticated attackers to export form submissions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
