The dependency declarations provide only minimum versions and no upper bounds, exact pins, or cryptographic hashes. The fallback installation command in
SKILL.mdis even less constrained because it directly installs the latest available versions oftushareandpandas.Package installation and import can execute code supplied by a dependency. Consequently, a future compromised, malicious, or unexpectedly incompatible release satisfying these constraints could run code that was not present during this audit. The package names are consistent with the Skill's declared functionality, and the audit found no evidence of typosquatting or an intentionally malicious current dependency. The risk arises from allowing mutable, unreviewed future versions.
Attack Path
- An attacker compromises the package publisher account, build infrastructure, or distribution channel for an allowed dependency.
- The attacker publishes a malicious version newer than the specified minimum.
- A user follows the documented installation instructions.
pipresolves and installs the malicious release because it satisfies the open-ended version constraint.- Malicious installation or runtime code executes with the privileges of the user running
pipor invoking the Skill.

Remediation Suggestions
-
Replace minimum-only constraints with exact versions that have been reviewed and tested.
-
Generate a lock file containing all transitive dependencies.
-
Record and enforce package hashes, such as through:
bash pip install --require-hashes -r requirements.txt -
Replace
pip install tushare pandasinSKILL.mdwith installation from the reviewed lock file. -
Install dependencies in a dedicated virtual environment rather than the system Python environment.
-
Use a trusted package index explicitly and prevent fallback to untrusted extra indexes.
-
Add automated dependency vulnerability and integrity scanning to the release process.
-
Review and deliberately update pinned versions on a controlled schedule.
