CVE-2025-6440Public exploitNetwork attack vector

Unauthenticated file upload via unchecked type metadata

Published Oct 24, 2025 · Updated Oct 24, 2025

Arbitrary file upload in JMA Plugins WooCommerce Designer Pro 1.9.26 and earlier allows remote attackers to write files to the server. The wcdp_save_canvas_design_ajax handler accepts attacker-controlled file type metadata and content without validating the file extension before storing the upload. Execution requires the uploaded file to be web-accessible and executable by the server; otherwise the direct consequence is an unauthenticated file write.
