- Unpinned Third-Party Dependency Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 64-67 **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Low **Vulnerable Code**: ```markdown ### 1) Install Dependency ```bash pip install requests ``` ``` ### Technical Analysis The installation instructions retrieve `requests` without specifying an audited version or verifying package integrity with cryptographic hashes. Dependency resolution can therefore produce different code over time, independently of the reviewed skill package. This does not establish that the current `requests` package is malicious. However, it creates a supply-chain weakness: if the package, its release process, the configured package index, or dependency resolution environment is compromised, following the documented command could install attacker-controlled code. Python packages and their transitive dependencies may execute code during installation or when imported. ### Attack Path 1. An attacker compromises a relevant package release, package index, dependency-resolution path, or transitive dependency. 2. A user follows the Quick Start instructions and runs `pip install requests`. 3. Because no version or integrity hash is specified, `pip` resolves and downloads the mutable package release selected by the configured index. 4. The compromised package executes code during installation, import, or subsequent use by `scripts/skill_router.py`. 5. The malicious code runs with the permissions of the user or service account operating the skill. ### Impact Assessment Successful exploitation could provide code execution within the installation or skill runtime context. The attacker could access files, environment variables, network resources, and credentials available to that user. This could include the `API_KEY` environment variable used by the skill. The maximum scope is limited by the privileges and isolation controls of the account or container running th ...[truncated 178 chars]
- Remediation
- ## Remediation Suggestions 1. Declare dependencies in a version-controlled requirements or lock file using an explicitly reviewed version. 2. Record cryptographic hashes for all direct and transitive dependencies. 3. Install packages with hash verification enabled, for example: ```bash pip install --require-hashes -r requirements.txt ``` 4. Generate and review the lock file through a controlled dependency-management process, and update it only after security review and testing. 5. Use a trusted package index and prevent fallback to unapproved indexes. 6. Run installation and the skill in an isolated virtual environment or container under a least-privileged account. 7. Add automated dependency vulnerability and provenance checks to the release workflow.
