- Vector: CVSS:3.1/AV:P/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- ZTE Blade A75 5G: version range not reported

## 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.
