Arbitrary File Write Vulnerability in Hippoo Mobile App for WooCommerce Plugin by WordPress

CVE-2025-12655

What is CVE-2025-12655?

The Hippoo Mobile App for WooCommerce plugin for WordPress is susceptible to arbitrary file write due to a critical authorization oversight in its REST API endpoint. All versions up to and including 1.7.1 allow unauthenticated users to access the endpoint /wp-json/hippoo/v1/wc/token/save_callback/{token_id} without any permission checks. This vulnerability enables attackers to write arbitrary JSON content to the server's upload directory, potentially leading to further exploitation of the platform.
