CVE-2025-12674 is a critical arbitrary file upload vulnerability in the KiotViet Sync plugin for WordPress affecting all versions up to and including 1.8.5. The flaw is caused by missing file type validation in the plugin's create_media() function. As described in the provided content, the vulnerable upload handling allows an unauthenticated remote attacker to submit crafted upload requests and store arbitrary files on the target server, including potentially executable files such as PHP scripts. If the uploaded file is placed in a web-accessible location, the attacker may then directly request it and achieve remote code execution on the affected WordPress site.

This repository contains a Python exploit script (CVE-2025-12674.py) targeting the KiotViet Sync WordPress plugin (versions <= 1.8.5), which is vulnerable to unauthenticated arbitrary file upload due to missing file type validation. The exploit allows an attacker to upload a remote shell (e.g., a PHP webshell) to the target's WordPress uploads directory by abusing the /wp-json/admin/v1/query API endpoint. The script is multithreaded, supports batch exploitation via a list of targets (list.txt), and saves successful shell upload locations to shells.txt. The exploit is operational and requires the attacker to provide a URL to a remote shell file. The repository also includes a README with detailed usage instructions, a license file, and a requirements.txt specifying Python dependencies (requests, rich).
