What it is: CVE-2022-39071 is a high-severity missing authorization vulnerability in ZTE Blade A52, ZTE Blade A51, ZTE Blade A3 Lite, ZTE Blade A5 2020, ZTE Blade L210, ZTE Blade A7s, ZTE Blade A31, ZTE Blade A31 Plus, ZTE Blade A5 (2019), ZTE Blade A71, ZTE Blade A72, ZTE Blade V20 Smart, ZTE Blade V30, ZTE Blade V30 Vita, ZTE V40 Pro, ZTE Blade V40 Vita, ZTE Axon 40 Ultra, published on 30 May 2023. 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-2022-39071 in the wild and no public exploit code.

Affected product: ZTE Blade A52, ZTE Blade A51, ZTE Blade A3 Lite, ZTE Blade A5 2020, ZTE Blade L210, ZTE Blade A7s, ZTE Blade A31, ZTE Blade A31 Plus, ZTE Blade A5 (2019), ZTE Blade A71, ZTE Blade A72, ZTE Blade V20 Smart, ZTE Blade V30, ZTE Blade V30 Vita, ZTE V40 Pro, ZTE Blade V40 Vita, ZTE Axon 40 Ultra. 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.
