Vulnerability Type: Insecure dependency installation and supply-chain exposure
Risk Level: MediumComplete Code Snippet:
bash pip install django djangorestframeworkTechnical Analysis
The Skill instructs users to install
djangoanddjangorestframeworkwithout pinning reviewed versions, validating package hashes, or explicitly identifying a trusted package repository. Pip will therefore select mutable package versions from whichever index is configured in the user's environment.Installing these dependencies is necessary for the Skill's declared Django REST Framework scaffolding functionality, and both package names correspond to established projects. However, the instruction lacks standard dependency-integrity and reproducibility controls. If a package release, transitive dependency, configured package index, or package-distribution account is compromised, following the instruction could install attacker-controlled content.
The command does not explicitly transmit credentials, private keys, source code, environment variables, or other sensitive information. Therefore, the pre-scan warning concerning sensitive-information transmission is not substantiated by the reviewed content. The relevant confirmed risk is dependency supply-chain exposure.
Attack Path
- An attacker compromises a selected package release, one of its transitive dependencies, its distribution account, or a package index configured in the user's pip environment.
- A user follows the Skill and runs the unpinned installation command.
- Pip resolves the current package artifacts using the implicit index and installs them without checking project-provided hashes.
- A malicious artifact executes installation-related behavior where applicable or introduces malicious runtime code.
- The malicious code subsequently runs with the privileges of the user executing pip ...[truncated 900 chars]

Remediation Suggestions
- Replace the direct unpinned installation command with a reviewed requirements or lock file containing exact versions.
- Generate and record cryptographic hashes for all direct and transitive dependencies, then install with:
bash python3 -m pip install --require-hashes -r requirements.txt - Document the expected trusted package index and avoid relying silently on user-specific pip configuration. Where appropriate, use an explicitly approved internal mirror.
- Regularly review and update pinned versions to receive security fixes rather than leaving pins indefinitely stale.
- Run dependency vulnerability scanning in CI using a maintained tool such as
pip-audit. - Perform installation in an isolated virtual environment under a non-privileged account, as already partially encouraged by the Skill, and explicitly warn users not to run pip as root or with elevated privileges.
- If a tutorial must permit flexible versions, specify reviewed compatible version ranges and explain that production deployments should use a fully resolved, hash-locked dependency set.
