Vulnerability Type:T08: Insecure Dependencies
Risk Level: Mediumjson "dependencies": ["akshare", "pandas"],Technical Analysis
The Skill declares
akshareandpandaswithout exact version constraints or integrity hashes. Consequently, installations performed at different times may resolve to unreviewed releases with changed or compromised code.Both packages are imported directly by
capital_flow.py. Python executes package initialization code during import, meaning a compromised dependency release could run code in the Skill process before the intended analysis functions execute. The project also lacks a lockfile or other recorded integrity mechanism that would ensure reproducible, reviewed dependency resolution.Attack Path
- An attacker compromises a future release of one of the declared packages or its package-distribution channel.
- The Skill is installed or rebuilt while its dependencies remain unconstrained.
- The package manager resolves and installs the attacker-controlled release.
capital_flow.pyimports the affected package.- Malicious package initialization code executes with the permissions and environment access of the Agent process.
This path depends on compromise of a dependency or its distribution channel; the audited project does not itself contain an embedded malicious payload.
Impact Assessment
A compromised dependency could execute arbitrary Python code under the Agent process identity. Depending on the hosting environment, this could permit access to files, environment variables, network resources, or credentials available to that process. It could also manipulate returned financial-analysis results or disrupt Skill availability.
The maximum scope is limited by the operating-system permissions, network access, secrets, and sandbox boundaries granted to the Agent process.

Remediation Suggestions
- Pin each direct dependency to a reviewed exact version rather than accepting arbitrary future releases.
- Generate and commit a lockfile containing resolved transitive dependency versions.
- Require cryptographic hashes during installation, such as with a hash-locked requirements file.
- Install packages only from an approved package index over authenticated TLS; disable untrusted extra indexes.
- Scan direct and transitive dependencies for known vulnerabilities and review changes before upgrades.
- Remove the unused direct
pandasimport and dependency if it is not otherwise required, reducing the exposed supply-chain surface. - Run the Skill with least privilege and restrict filesystem, credential, and network access to limit the impact of any dependency compromise.
