SKILL.md, lines 86–92
Vulnerability Type: Unpinned and unverified third-party dependency
Risk Level: MediumVulnerable Code Snippet:
bash pip install --upgrade thsdkmarkdown > Package source: [PyPI](https://pypi.org/project/thsdk/)Technical Analysis
The installation instructions use
--upgradewithout specifying a reviewed package version or verifying package hashes. Consequently, users receive whicheverthsdkrelease is current at installation time rather than the version assessed during development.The example programs import
THSfrom this package and execute its functionality. If the package, its publisher account, or its dependency chain were compromised, a malicious release could execute code during installation or when the examples instantiate and useTHS. Merely naming PyPI as the package source does not provide artifact integrity or ensure that future releases remain trustworthy.Attack Path
- An attacker compromises the
thsdkpublisher account, package release process, or dependency chain. - The attacker publishes a malicious version that becomes the latest available release.
- A user follows the documented
pip install --upgrade thsdkinstruction. - The package manager downloads and installs the malicious release without version or hash validation.
- Malicious installation hooks or runtime code execute when the package is installed, imported, or used by the supplied examples.
Impact Assessment
Exploitation could execute code with the permissions of the user running
pipor the example scripts. Depending on that user's environment and privileges, the compromised dependency could read or modify accessible files, access process environment data, falsify financial-analysis results, make unauthorized network requests, or install additional malicious components.The repository itself contains no observed malicious payload.

Remediation Suggestions
- Pin
thsdkto a specifically reviewed version rather than installing the latest release:
text thsdk==REVIEWED_VERSION- Record cryptographic hashes in a requirements file and enforce verification:
bash pip install --require-hashes -r requirements.txt-
Commit a lock file or fully resolved dependency manifest so transitive dependencies are reproducible.
-
Document the verified publisher and official source repository, and compare release artifacts against the reviewed source.
-
Review dependency updates before changing the pinned version. Use automated vulnerability and provenance scanning as part of that review.
-
Prefer installation in an isolated virtual environment with minimal filesystem and credential access. Avoid running package installation or examples with administrative privileges.
