CVE-2021-4375Network attack vector

Authenticated settings disclosure via missing capability check

Published Jun 7, 2023 · Updated Apr 8, 2026

Missing authorization in Welcart e-Commerce before 2.2.8 allows remote authenticated users to download server and application settings. The usces_download_system_information() AJAX handler exports WordPress, plugin, PHP, and server settings without checking the caller's capability. A low-privileged WordPress account is sufficient, and the disclosure exposes configuration details without changing data or service state.
