Vulnerability Type: Unpinned third-party package installation
Risk Level: MediumVulnerable Code:
bash pip install pandas numpy scikit-learn xgboost lightgbm scipy statsmodels pip install akshare tushareTechnical Analysis
The documented installation commands install multiple packages without fixed versions or cryptographic integrity hashes. Consequently, the exact code installed depends on package-index contents and dependency resolution at installation time.
This makes installations non-reproducible and creates exposure to compromised package releases, malicious transitive dependencies, dependency-resolution changes, or an untrusted package index. Python packages may execute installation-related code, and imported packages execute module initialization code. A compromised dependency could therefore run attacker-controlled code in the user's environment.
The audit did not identify evidence that any currently named package is malicious. The vulnerability is the absence of controls ensuring that users receive specifically reviewed package artifacts.
Attack Path
- An attacker compromises a named package, one of its transitive dependencies, or a package index used by the victim.
- The attacker publishes or serves a malicious release that satisfies the unconstrained dependency request.
- A user follows the installation instructions in
SKILL.md. pipresolves and downloads the attacker-controlled package artifact.- Malicious code executes during package installation or when the package is subsequently imported.
- The payload operates with the privileges and environment access of the user running
pipor the research platform.
Impact Assessment
Successful exploitation could provide arbitrary code execution with the installing user's privileges. Depending on that user's permissions and environment, an attack ...[truncated 440 chars]

Remediation Suggestions
- Move direct dependencies into a reviewed requirements or project configuration file and pin each package to an approved version.
- Generate a lock file that also constrains transitive dependencies.
- Record and enforce artifact hashes, for example by using:
bash pip install --require-hashes -r requirements.txt - Retrieve packages only from an approved HTTPS package index or an internally controlled artifact repository.
- Disable unintended fallback to additional or user-controlled package indexes.
- Run dependency vulnerability and provenance checks in continuous integration, and update pins through a controlled review process.
- Install dependencies inside an isolated virtual environment or container under a non-privileged account.
- Review new package versions before updating the lock file, including changes to transitive dependencies and package ownership.
