## What is CVE-2025-63434?

CVE-2025-63434 is a high-severity code injection vulnerability in n/a, published on 24 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The update mechanism in Xtooltech Xtool AnyScan Android Application 4.40.40 and prior is insecure. The application downloads and extracts update packages containing executable code without performing a cryptographic integrity or authenticity check on their contents. An attacker who can control the update metadata can serve a malicious package, which the application will accept, extract, and later execute, leading to arbitrary code execution.

Weakness: CWE-494 (Download of Code Without Integrity Check)

Check this codebase for CVE-2025-63434 and fix it if it is affected.

What it is: CVE-2025-63434 is a high-severity code injection vulnerability in n/a, published on 24 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-63434 in the wild and no public exploit code.

Affected product: n/a. 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.
