Description
The SimpleForm – Form Maker to Chat Apps with Quiz, Poll and Multi Lead Notifications WordPress plugin up to version 3.10.2 contains an arbitrary file upload vulnerability. This flaw allows unauthenticated attackers to upload potentially executable files by bypassing extension and MIME type validation through a trailing-dot filename. The vulnerability arises from missing server-side file key allowlist and inadequate pre-sanitization in the handle_upload function. The only access control is a nonce embedded in public forms, which is easily obtainable by any visitor, enabling remote code execution.
