- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `SKILL.md:28-31` **Vulnerability Type**: Unpinned dependency installation from a public package registry **Risk Level**: Medium **Vulnerable Code**: ```markdown - `ib_insync` installed: ```bash pip install ib_insync ``` ``` ### Technical Analysis The documented installation command resolves and installs the latest version of `ib_insync` available from pip's configured package index. It does not constrain the dependency to a reviewed version, validate an integrity hash, use a lock file, or identify a trusted package source. Package installation and subsequent imports can execute third-party code with the privileges of the user running pip or the trading CLI. Consequently, the effective code installed by this procedure can change after the Skill has been audited. Exploitation would require compromise of the package distribution channel, the package publisher, a configured package index, or the dependency resolution environment. ### Attack Path 1. An attacker compromises a future `ib_insync` release, its publisher account, a package index used by the victim, or the victim's dependency-resolution path. 2. The victim follows the documented `pip install ib_insync` command. 3. pip resolves the attacker-controlled or compromised release because no reviewed version or hash is required. 4. Malicious package code executes during installation or when `ib_insync` is imported by `scripts/ibkr_cli.py`. 5. The malicious code operates with the installing or CLI user's privileges and may access resources available in that execution environment. ### Impact Assessment Successful exploitation could provide arbitrary Python code execution with the privileges of the user installing or running the package. The accessible scope could include local files, environment variables, network resources, and the local IBKR TWS/Gateway session available to that user.

- Remediation
- ## Remediation Suggestions 1. Pin `ib_insync` to a specifically reviewed version rather than installing the latest release implicitly. 2. Place the dependency in a version-controlled requirements file with cryptographic hashes, for example: ```text ib_insync==<reviewed-version> --hash=sha256:<verified-hash> ``` 3. Install it using hash enforcement: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 4. Record and verify the expected package index, package publisher, and artifact provenance. 5. Review transitive dependencies and pin them through a generated lock file. 6. Perform installation in an isolated virtual environment using a non-privileged account. 7. Test dependency upgrades against an IBKR paper-trading environment before approving them for production use. 8. Configure TWS or IB Gateway with the minimum necessary API permissions and use read-only mode for commands that do not require trading access.
