CVE-2025-13329Network attack vectorHinoki check available

Unauthenticated file upload via unchecked REST callback

Published Dec 20, 2025 · Updated Dec 20, 2025

Arbitrary file upload in Snowray Software File Uploader for WooCommerce 1.0.3 and earlier allows remote attackers to place dangerous files. The add-image-data REST callback accepts attacker-controlled upload metadata without validating the file type, sends the file to Uploadcare, and later downloads it onto the WordPress server. No authentication or user interaction is required; server-side code execution depends on the downloaded file being executable in the site's hosting configuration.
