- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `templates/trading-signals.md`, line 17 **Vulnerability Type**: Unpinned third-party dependencies **Risk Level**: Medium ```bash pip install MetaTrader5 pandas numpy ``` ### Technical Analysis The installation command resolves the latest available versions of three third-party packages without version constraints, cryptographic hashes, a lockfile, or an explicitly trusted package index. Consequently, the code installed by users can differ from the code that was available when the skill was reviewed. Python packages can execute package-controlled build or installation logic and later execute code when imported. If a dependency, its release process, or one of its transitive dependencies is compromised, following this instruction could introduce attacker-controlled code into the user's environment. This finding identifies a supply-chain weakness. The reviewed files do not establish that any named package is currently malicious. ### Attack Path 1. An attacker compromises a dependency release, maintainer account, distribution process, or transitive dependency. 2. The attacker publishes a malicious package version to the package index used by `pip`. 3. A user follows the documented installation command. 4. Because no versions or hashes are specified, `pip` may resolve and install the attacker-controlled release. 5. Malicious code executes during package installation, package import, or use of the trading functionality. ### Impact Assessment Malicious dependency code could run with the privileges of the user executing `pip` or importing the package. Depending on those privileges and the surrounding environment, this could permit access to local files, environment variables, API credentials, trading configuration, network resources, and any accounts accessible to that user. It could also modify files or establish additional malicious behavior. The scope is normally limited to the ...[truncated 221 chars]
- Remediation
- ## Remediation Suggestions 1. Move dependencies into a reviewed lockfile or requirements file and pin exact versions. 2. Require cryptographic hashes, for example through `pip install --require-hashes -r requirements.txt`. 3. Pin and audit transitive dependencies, not only the three direct dependencies. 4. Configure an explicitly trusted package index or an internally controlled package mirror. 5. Install packages in a dedicated virtual environment or restricted container rather than a privileged system environment. 6. Run dependency vulnerability and provenance checks in CI before publishing updates. 7. Review dependency updates before changing pins, then regenerate and verify hashes. 8. Avoid running `pip` as root or with administrator privileges.
