Kerentanan Unrestricted Upload of File with Dangerous Type pada vanquish woocommerce upload files. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

The WooCommerce Upload Files WordPress plugin before 59.4 ran a single sanitization pass to remove blocked extensions such as .php. It was possible to bypass this and upload a file with a PHP extension by embedding a "blocked" extension within another "blocked" extension in the "wcuf_file_name" parameter. It was also possible to perform a double extension attack and upload files to a different location via path traversal using the "wcuf_current_upload_session_id" parameter.
