Arbitrary File Upload in WooCommerce File Uploader Enables RCE

Publication date: 2025-12-20

Last updated on: 2026-04-08

Assigner: Wordfence

Description

The File Uploader for WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the callback function for the 'add-image-data' REST API endpoint in all versions up to, and including, 1.0.3. This makes it possible for unauthenticated attackers to upload arbitrary files to the Uploadcare service and subsequently download them on the affected site's server which may make remote code execution possible.

Attack-Flow Graph

Executive Summary

The vulnerability in the File Uploader for WooCommerce plugin allows unauthenticated attackers to upload arbitrary files because the plugin lacks proper file type validation in the 'add-image-data' REST API endpoint callback. This means attackers can upload potentially malicious files to the Uploadcare service and then download them onto the affected website's server, which could lead to remote code execution.

Impact Analysis

This vulnerability can have severe impacts including unauthorized file uploads that may lead to remote code execution on your server. This could allow attackers to execute malicious code, compromise your website, steal data, deface your site, or use your server for further attacks.

Mitigation Strategies

To mitigate this vulnerability, immediately update the File Uploader for WooCommerce plugin to a version later than 1.0.3 where the issue is fixed. If an update is not yet available, consider disabling or removing the plugin to prevent exploitation. Additionally, monitor your WooCommerce orders and uploaded files for any suspicious activity and restrict access to the 'add-image-data' REST API endpoint if possible.
