Vulnerability Type: Unpinned Python dependency and non-reproducible installation
Risk Level: MediumVulnerable Code:
bash # Install dependencies pip install requestsTechnical Analysis
The documented installation command retrieves the latest version of
requestsand its transitive dependencies without enforcing reviewed versions or package integrity hashes. Consequently, the code installed by this command may change over time even when the skill package itself remains unchanged.Because Python packages and their installation components execute with the privileges of the user running
pip, a compromised package release, compromised transitive dependency, or unexpected incompatible update could introduce arbitrary code into the skill's runtime environment. The repository does not provide a locked dependency manifest or hashes that would allow installers to verify that they received the versions reviewed by the project maintainer.This finding does not establish that the current
requestspackage is malicious. It identifies an avoidable supply-chain exposure caused by unconstrained dependency resolution.Attack Path
- An attacker compromises a future release of
requestsor one of its transitive dependencies, or otherwise causes a malicious package version to be selected from the configured Python package index. - A user follows the installation instructions and runs
pip install requests. - Pip resolves and downloads the attacker-controlled version because no version or integrity constraint is present.
- Malicious installation or runtime code executes under the installing user's account.
- That code can access resources available to the user, including project files, environment variables, local application data, and outbound network connections.

Remediation Suggestions
- Add a reviewed dependency manifest that pins
requestsand every transitive dependency to exact versions. - Generate and retain cryptographic hashes for all approved distributions.
- Install dependencies using hash verification, for example:
bash python3 -m pip install --require-hashes -r requirements.txt - Use a lock-file workflow such as
pip-tools, Poetry, or an equivalent reproducible dependency manager. - Configure automated dependency vulnerability scanning and review updates before regenerating the lock file.
- Recommend installation in a dedicated virtual environment rather than the system Python environment.
- Avoid running pip with administrator or root privileges.
- Add a reviewed dependency manifest that pins
