SureForms – Drag and Drop Form Builder for WordPress <= 1.7.3 - Unauthenticated Arbitrary File Deletion Triggered via Administrator Submission Deletion

The SureForms – Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_entry_files() function in all versions up to, and including, 1.7.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
