Vulnerability Type: Supply-chain exposure through unpinned dependencies
Risk Level: MediumVulnerable code snippet:
bash ## 安装依赖 ```bash # CLI pip install argparse # FastAPI pip install fastapi uvicorn # Flask pip install flask # Scraper pip install requests beautifulsoup4text ### Technical Analysis The installation instructions use mutable package names without exact versions, integrity hashes, a lock file, or a documented trusted package index. Consequently, installation results depend on whichever releases and package source are active when the commands are run. The instruction to install `argparse` is unnecessary on supported Python 3 versions because `argparse` is included in the standard library. Installing an external package with that name needlessly increases supply-chain exposure. This finding does not establish that the named packages are currently malicious. The weakness is that the documented process provides no controls against a future compromised release, unsafe index configuration, or dependency substitution. ### Attack Path 1. An attacker compromises a package release or gains influence over a package source available through the user's pip configuration. 2. The attacker publishes package content containing malicious installation or runtime behavior under a dependency name resolved by the documented commands. 3. A user follows the instructions in `SKILL.md` without a version lock or hash verification. 4. pip resolves and downloads the attacker-controlled or compromised release. 5. Malicious package behavior executes during installation or when the generated application imports and uses the dependency. ### Impact Assessment Malicious dependency code would generally execute with the privileges of the user or automation account running pip or the generated application.

Remediation Suggestions
- Remove
pip install argparse; use Python 3's standard-libraryargparsemodule. - Declare third-party dependencies in a maintained dependency manifest rather than relying solely on ad hoc installation commands.
- Pin reviewed versions exactly, for example with
package==x.y.z. - Generate and commit a lock file appropriate to the selected dependency-management tool.
- Require package hashes during reproducible installation, such as through a hash-locked requirements file and
pip install --require-hashes. - Document and enforce an approved package index rather than inheriting arbitrary user or CI index configuration.
- Add automated dependency vulnerability and integrity monitoring, with a controlled review process for upgrades.
- Recommend installation inside a dedicated virtual environment under a non-privileged account.
- Remove
