What to do

Update, patch or deactivate.

No fixed release is identified. Update Forminator Forms – Contact Form, Payment Form & Custom Form Builder when a release after 1.53.0 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 1.57.0, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Forminator Forms plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 1.53.0. This is due to the listen_for_saving_export_schedule() function in library/class-export.php failing to perform a capability check before saving the scheduled export configuration, unlike the parallel listen_for_csv_export() function which correctly verifies user permissions. This makes it possible for authenticated attackers with subscriber-level access to configure a scheduled export job that emails all form submissions to an attacker-controlled email address, resulting in sensitive data exfiltration.
