Unauthenticated file read via unchecked CSV URL
Published Jul 8, 2026 · Updated Jul 8, 2026
Path traversal in Bulk Order Update for WooCommerce 1.6 and earlier allows remote attackers to read the first line of server files. The public bouw_fetch_csv_data() AJAX handler passes csv_url through filters that leave absolute paths intact, then opens it with fopen() and returns the first fgetcsv() row. No authentication or user interaction is required; disclosure is limited to the first parsed line, while response differences expose file existence.
