- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `README.md`, lines 46–50 **Vulnerability Type**: Unpinned and unverifiable third-party dependency **Risk Level**: Medium ### Vulnerable Code ```markdown ### 4. Install Dependencies The script uses Python 3 and the `requests` library. ```bash pip3 install requests ``` ``` ### Technical Analysis The documented installation command retrieves the latest available version of `requests` from the package index configured for the user's Python environment. The project provides no version constraint, lockfile, integrity hash, explicit trusted index, or isolated-environment requirement. Consequently, installations are not reproducible and implicitly trust both the configured package index and the dependency version available at installation time. If the package source, package maintainer account, index configuration, or network trust boundary is compromised, unintended code could be installed. Python packages can execute code during installation and whenever imported; `scripts/crisp.py` imports `requests` at startup. This finding is limited to supply-chain hardening. The audited code does not itself download or execute an unknown remote payload at runtime. ### Attack Path 1. An attacker compromises a relevant package distribution account or causes the victim's pip configuration to reference an attacker-controlled index or mirror. 2. The user follows the documented `pip3 install requests` command. 3. Because no reviewed version or integrity hash is required, pip resolves and installs the package supplied by the selected index. 4. Malicious code executes during package installation or later when `scripts/crisp.py` imports `requests`. 5. The payload runs with the privileges of the user performing the installation or invoking the Skill. ### Impact Assessment Successful exploitation could provide arbitrary code execution under the Skill operator's account.

- Remediation
- ## Remediation Suggestions 1. Add a reviewed, version-pinned dependency file, such as: ```text requests==<reviewed-version> ``` 2. Generate and enforce cryptographic hashes for the package and its transitive dependencies, then install with: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 3. Commit a lockfile or fully hashed requirements file so installations are reproducible. 4. Install dependencies inside a dedicated virtual environment rather than the system Python environment. 5. Use an explicitly configured trusted package index or an internally controlled package mirror. 6. Periodically review and update pinned versions after vulnerability and compatibility testing. 7. Document that credentials should be injected only at runtime and should not be present while installing dependencies.
