- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `SKILL.md:8-11` **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Medium ### Vulnerable Code ```markdown Install dependencies: ```bash pip install akshare ``` ``` ### Technical Analysis The documented installation command retrieves and installs the current `akshare` release without an exact version constraint or package-integrity hash. Consequently, the installed code can differ over time from the version reviewed during this audit. Python packages can execute code during installation and whenever their modules are imported. If the upstream package, maintainer account, release process, or package repository is compromised, following this instruction could introduce attacker-controlled code into the user's environment. Unexpected upstream changes could also cause compatibility or integrity failures even without malicious activity. The audit found no evidence that AkShare itself is malicious. The risk arises from trusting mutable third-party package content without version or integrity verification. ### Attack Path 1. An attacker compromises the upstream AkShare release process, a maintainer account, or the package-distribution channel. 2. The attacker publishes a malicious release under the legitimate package name. 3. A user follows the skill documentation and runs `pip install akshare`. 4. Because no version or hash is specified, pip resolves and installs the attacker-controlled release. 5. Malicious package code executes during installation or when `scripts/stock_cli.py` imports `akshare`. 6. The payload operates with the permissions of the user or service account that installed or invoked the skill. ### Impact Assessment Successful exploitation could permit arbitrary Python code execution with the privileges of the installing or executing account. Depending on those privileges, the attacker could access files and environment variables available to that account, alter application dat ...[truncated 272 chars]
- Remediation
- ## Remediation Suggestions 1. Pin AkShare to an exact, reviewed version, for example through a dedicated requirements file: ```text akshare==<reviewed-version> ``` 2. Generate and verify cryptographic hashes for all direct and transitive dependencies, then install with hash enforcement: ```bash python -m pip install --require-hashes -r requirements.txt ``` 3. Maintain a lock file generated from a trusted environment so dependency resolution is reproducible. 4. Install packages only from an explicitly configured, trusted package index. 5. Review dependency updates before changing the pinned version, including release provenance and vulnerability advisories. 6. Perform installation and execution inside an isolated virtual environment or container under a non-privileged account.
