### Official description

An application "com.pri.applock", which is pre-loaded on Kruger&Matz smartphones, allows a user to encrypt any application using user-provided PIN code or by using biometric data.
Exposed ”com.pri.applock.LockUI“ activity allows any other malicious application, with no granted Android system permissions, to inject an arbitrary intent with system-level privileges to a protected application. One must know the protecting PIN number (it might be revealed by exploiting CVE-2024-13916) or ask the user to provide it.

Only version (version name: 13, version code: 33) was tested and confirmed to have this vulnerability.

What it is: CVE-2024-13917 is a high-severity missing authorization vulnerability in Kruger&Matz com.pri.applock, published on 30 May 2025. 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-2024-13917 in the wild and no public exploit code.

Affected product: Kruger&Matz com.pri.applock. 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.
