text akshare pandasTechnical Analysis
The project declares
akshareandpandaswithout exact versions or integrity hashes. Consequently, each installation can resolve to the newest version available at that time rather than a version reviewed and tested by the project maintainers.This creates a supply-chain risk because a compromised, malicious, or unexpectedly incompatible future release could be installed automatically. Python packages may execute code during installation or when imported. The Skill imports both packages in
SKILL.md, so any malicious runtime initialization shipped by a resolved dependency would execute in the Skill's process context.The audit did not establish that the current official releases of these packages are malicious. The confirmed weakness is the absence of dependency version and integrity controls.
Attack Path
- An attacker compromises an upstream dependency release or its package publishing account.
- The attacker publishes a malicious version under the legitimate package name.
- A user installs the project dependencies from
requirements.txt. - Because no version or hash is specified, the package installer resolves the attacker-controlled release.
- Malicious installation hooks or import-time code execute with the privileges of the user or Agent running the installation or Skill.
Impact Assessment
Successful exploitation could allow arbitrary code execution with the privileges of the process installing or running the Skill. Depending on that account's permissions, the malicious dependency could access readable files, environment variables, credentials, network resources, and data available to the Agent. The potential scope is the host environment and resources accessible to that process; this project itself doe ...[truncated 50 chars]

Remediation Suggestions
-
Pin each direct dependency to an exact, reviewed version, for example:
text akshare==<reviewed-version> pandas==<reviewed-version> -
Generate a lock file containing all transitive dependencies so installations remain reproducible.
-
Require package integrity hashes and install with hash verification, such as
pip install --require-hashes -r requirements.txt. -
Retrieve packages only from an explicitly configured, trusted package index.
-
Review dependency updates before modifying the lock file, including release changes, package provenance, and known vulnerability reports.
-
Run installation and execution in an isolated, least-privileged environment without unnecessary credentials or filesystem access.
