Description
The Innovative Form Builder – IvyForms WordPress plugin (versions up to 1.5.1) contains an arbitrary file upload vulnerability due to insufficient file type validation. Authenticated users with custom-level access can configure file upload fields to allow dangerous file extensions like PHP. This enables unauthenticated visitors to upload potentially executable files via a public REST API endpoint, leading to possible remote code execution.
