## 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 (Improper Limitation of a Pathname to a Restricted Directory)

What it is: 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.
Exploitation: There is no known exploitation of CVE-2026-40000 in the wild and no public exploit code.

Affected product: ZTE Blade A75 5G. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
