Bit Form – Custom Contact Form, Multi Step, Conversational Form & Payment Form Builder

The Bit Form builder plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 2.20.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. For this to be exploitable, the PRO version needs to be installed and activated as well. Additionally a form with an advanced file upload element needs to be published.

The Bit Form – Contact Form Plugin plugin for WordPress is vulnerable to unauthorized workflow execution due to missing authorization in the triggerWorkFlow function in all versions up to, and including, 2.21.6. This is due to a logic flaw in the nonce verification where the security check only blocks requests when both the nonce verification fails and the user is logged in. This makes it possible for unauthenticated attackers to replay form workflow executions and trigger all configured integrations including webhooks, email notifications, CRM integrations, and automation platforms via the bitforms_trigger_workflow AJAX action granted they can obtain the entry ID and log IDs from a legitimate form submission response.
