- Unpinned Third-Party Dependencies Create Supply-Chain Risk## Vulnerability Details **File Location**: `scripts/advanced.py:10-15` and `scripts/advanced.py:23-27` **Vulnerability Type**: Unpinned third-party dependencies **Risk Level**: Medium **Vulnerable code:** ```python Requires: - google-cloud-dialogflow-cx - google-auth Install: pip install google-cloud-dialogflow-cx google-auth ``` ```python except ImportError: print("Error: google-cloud-dialogflow-cx not installed") print("Run: pip install google-cloud-dialogflow-cx google-auth") sys.exit(1) ``` ### Technical Analysis The project instructs users to install `google-cloud-dialogflow-cx` and `google-auth` without exact version constraints or package integrity hashes. Consequently, `pip` resolves whichever package versions and transitive dependencies are available from the configured package index at installation time. The effective executable dependency set can therefore change after this skill has been reviewed. This does not establish that the named packages are currently malicious. However, if a future release, transitive dependency, configured package index, or dependency resolution path is compromised, installation or import of the resolved code could execute attacker-controlled Python under the privileges of the user running the skill. The absence of a lock file and hashes also prevents reliable verification that users install the same dependency artifacts that were security-reviewed and tested. ### Attack Path 1. An attacker compromises a future dependency release, one of its transitive dependencies, or a package index used by the victim. 2. A user runs the recommended command: `pip install google-cloud-dialogflow-cx google-auth`. 3. Because no versions or hashes are specified, `pip` resolves and installs the attacker-controlled or compromised artifact. 4. Malicious code can run during package installation or when `advanced.py` imports the installed p ...[truncated 686 chars]
- Remediation
- ## Remediation Suggestions 1. Pin every direct dependency to an exact, reviewed version rather than installing an unconstrained latest release. 2. Generate and commit a dependency lock file that captures all transitive dependency versions. 3. Record and enforce cryptographic hashes for downloaded artifacts, such as through a hash-locked `requirements.txt` installed with `pip --require-hashes`. 4. Replace the runtime error message with installation instructions that reference the reviewed lock file, for example: ```bash python -m pip install --require-hashes -r requirements.txt ``` 5. Obtain packages only from a trusted, explicitly configured index and consider using an internally mirrored repository containing approved artifacts. 6. Automate dependency vulnerability scanning and controlled update review. Regenerate hashes and rerun security tests whenever dependencies are upgraded. 7. Run the CLI with least-privilege Google credentials and in an isolated virtual environment to reduce the scope of a dependency compromise.
