Unrestricted file upload in Bit Apps Bit Form 2.13.3 and earlier allows remote authenticated users to place arbitrary files on the server. The iconUpload handler stores uploaded icon content without validating its file type, allowing dangerous extensions to reach the WordPress host. Administrator-level access is required; code execution follows only when the web server processes an uploaded file as executable content.
