Related Installation Instruction:SKILL.md:21-23
Vulnerability Type: Supply-chain exposure through non-reproducible dependency resolution
Risk Level: MediumVulnerable code:
text requests>=2.28.0 urllib3>=1.26.0 beautifulsoup4>=4.11.0 pyyaml>=6.0The dependencies are installed through the following documented command:
bash # 1. Install dependencies pip install -r requirements.txtTechnical Analysis
Every dependency uses an open-ended minimum-version constraint. Consequently, installation resolves the latest compatible packages available from the configured Python package index at installation time rather than a fixed, previously reviewed dependency set.
This does not prove that any currently named dependency is malicious. However, it makes builds non-reproducible and permits future, unreviewed direct or transitive versions to enter the execution environment. If an upstream distribution account, package release, package index, or dependency is compromised, malicious installation-time or import-time code could execute under the installing user's account.
No hashes or lock file are supplied to authenticate the expected package artifacts.
Attack Path
- An attacker compromises a permitted future release, an upstream distribution account, a transitive dependency, or the package source used by pip.
- A user follows
SKILL.mdand runspip install -r requirements.txt. - pip resolves the compromised release because it satisfies the open-ended
>=constraint. - Malicious package installation hooks or subsequently imported code execute with the privileges of the user running pip or the monitor.
- The compromised code could access process-readable files and configuration, alter monitoring results, or initiate network connections.

Remediation Suggestions
-
Pin every direct dependency to an exact reviewed version using
==. -
Generate a lock file that also fixes all transitive dependency versions.
-
Record cryptographic hashes for every permitted artifact and install with:
bash python -m pip install --require-hashes -r requirements.lock -
Generate the lock file through a controlled workflow, such as
pip-compile --generate-hashes, and review dependency changes before updating it. -
Install inside a dedicated virtual environment under an unprivileged account; do not run pip with administrator or root privileges.
-
Use a trusted package index and prevent unintended fallback to untrusted extra indexes.
-
Add automated dependency vulnerability and integrity scanning to the release process.
