What is CVE-2026-40000?
CVE-2026-40000 is a low-severity path traversal vulnerability in ZTE Blade A75 5G, published on 27 Jul 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
The Activity zte.com.cn.filer/zte.com.cn.filer.FilePreViewActivity within ZTE File Manager is designed to preview compressed files. Third-party applications can launch this Activity and supply arbitrary file paths (e.g., content://zte.com.cn.filer.fileprovider/root_path), enabling file access with the privilege level of ZTE File Manager. This allows unrooted devices to read files under certain system directories such as /data/data and /data/local/tmp. If access restrictions do not block untrusted applications, additional directories may also be accessible.
Weakness: CWE-22
