FlowForms <= 1.1.1 - Authenticated (Contributor+) Insecure Direct Object Reference to Arbitrary Form Modification via REST API '/flowforms/v1/forms/{id}' Endpoints

Summary

The FlowForms – Conversational Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.1.1 via the update_form due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to modify the content, design, and settings of, as well as publish or revert, any form on the site — including forms owned by administrators — by supplying an arbitrary form ID in the REST URL.
