The Skill requires operators to install dependencies using the active pip package index, while every dependency is constrained only by a lower version bound. There is no lockfile, exact version pinning, package hash verification, or trusted-index restriction.
Consequently, future package releases that satisfy the
>=constraints can be installed without having been reviewed with the Skill. If an upstream package, maintainer account, build artifact, or configured package index is compromised, malicious code may execute during package installation, build processing, or subsequent import byscripts/main.py.This risk is especially significant because the application initializes Alibaba Cloud's credential chain. A malicious dependency running in the same process could access environment variables, local credential configuration, and the authenticated SDK execution context.

Remediation Suggestions
- Replace lower-bound constraints with exact, reviewed versions:
text alibabacloud_credentials==X.Y.Z alibabacloud_tea_openapi==X.Y.Z - Generate a fully resolved lockfile that includes all transitive dependencies.
- Record cryptographic hashes for every distribution and install with:
bash python3 -m pip install --require-hashes -r requirements.lock - Restrict installation to an approved package index or internal artifact repository using explicit index configuration.
- Review and scan dependency updates before changing locked versions.
- Run dependency installation and the Skill in an isolated virtual environment or container under a non-privileged user.
- Use short-lived, least-privilege Alibaba Cloud credentials and grant only the documented read-only API permissions.
- Separate dependency installation from credential-bearing execution where practical, so package build or installation steps cannot access cloud credentials.
- Add automated software-composition analysis, provenance verification, and recurring vulnerability monitoring to the release process.
- Replace lower-bound constraints with exact, reviewed versions:
