Vulnerability Type: Unpinned and unverified third-party dependencies
Risk Level: MediumThe documentation instructs users to install multiple Python packages without version constraints, integrity hashes, a lockfile, or an explicitly trusted package source.

Running
pip installwith an unpinned package name resolves whichever release the configured package index currently presents as appropriate. The project supplies no reviewed version constraints, cryptographic hashes, or lockfile to ensure that users install the same dependency artifacts that were assessed by the project author.Python package installation can execute package-controlled build or installation logic. A compromised package release, transitive dependency, package repository, or local pip index configuration could therefore introduce attacker-controlled code. The risk is significant for these dependencies because they provide access to Windows APIs and keyboard, mouse, and GUI automation capabilities.
The audit found no evidence that the named packages are currently malicious. The vulnerability is the unsafe and mutable dependency installation process rather than a confirmed compromise of a particular package.
Attack Path
- An attacker compromises a named dependency, one of its transitive dependencies, or a package source trusted by the victim's pip configuration.
- The attacker publishes or serves a malicious distribution under a dependency name accepted by the unpinned installation command.

Remediation Suggestions
- Pin every direct dependency to a reviewed, exact version rather than using unconstrained package names.
- Create a lockfile or hash-locked requirements file containing all direct and transitive dependencies.
- Install with hash enforcement, for example:
bash python -m pip install --require-hashes -r requirements.txt - Document the approved package index and use an explicitly configured trusted repository rather than relying on ambient pip configuration.
- Verify package provenance and review release metadata before updating pinned versions.
- Perform dependency updates through a controlled review process that includes vulnerability scanning and testing.
- Install and run the toolkit in a dedicated virtual environment under a non-administrative account whenever possible.
- Require elevation only for the specific operations that need it, and do not run package installation with administrator privileges without a documented necessity.
