Vulnerability Type: Supply-chain exposure through non-deterministic dependency resolution
Risk Level: MediumVulnerable Code
text requests>=2.31.0 beautifulsoup4>=4.12.0 lxml>=5.0.0 python-dotenv>=1.0.0Technical Analysis
Every dependency is constrained only by a minimum version. Consequently, the installation command documented in
SKILL.mdcan resolve to any future release satisfying these constraints. The project also provides no integrity hashes to verify downloaded distributions.This makes dependency installation non-reproducible and allows the effective third-party code executed by the Skill to change without any modification to the audited repository. Although no malicious package is currently identified in the supplied files, compromise of a permitted future release or its distribution channel could introduce malicious installation-time or runtime behavior.
Attack Path
- An attacker compromises the publisher account, build pipeline, or distribution artifact of one of the listed packages.
- The attacker publishes a malicious version whose version number satisfies the applicable
>=constraint. - A user follows the documented command
python -m pip install -r requirements.txt. - Pip resolves and installs the malicious or compromised release because no exact version or artifact hash is enforced.
- Malicious package code can execute during installation or when the script imports the dependency.
- That code runs with the privileges of the user performing installation or invoking the Skill.
Impact Assessment
A compromised dependency could access data and resources available to the invoking user. In this Skill, that scope may include the Zhipu API key, CEAC case number, passport number, surname, environment variables, local files accessible to the process, and outbound network connectivity.

Remediation Suggestions
- Replace minimum-version constraints with exact, reviewed versions, for example:
text requests==2.32.5 beautifulsoup4==4.13.5 lxml==6.0.1 python-dotenv==1.1.1- Generate a lock file containing hashes for every direct and transitive dependency, and install with hash enforcement:
bash python -m pip install --require-hashes -r requirements.lock- Produce the lock file through a controlled dependency-management process such as
pip-compile --generate-hashes. - Review release notes and security advisories before updating pinned versions.
- Run dependency vulnerability scanning in CI and reject unexpected dependency-tree changes.
- Install and execute the Skill in an isolated, non-privileged virtual environment with access only to the files and secrets required for the CEAC query.
