- Unbounded Third-Party Dependency Permits Unaudited Future Releases<![CDATA[ ## Vulnerability Details **File Location**: `package.json:25-28` **Vulnerability Type**: Unbounded third-party dependency / supply-chain exposure **Risk Level**: Medium ### Vulnerable Code ```json "requires": { "bins": ["python3"], "pips": ["garminconnect>=0.2.38"] }, ``` The same unsafe installation pattern is documented in `README.md:69`, `SKILL.md:11`, and `SKILL.md:94`: ```bash pip3 install garminconnect ``` ### Technical Analysis The Skill permits any current or future `garminconnect` release greater than or equal to version `0.2.38`. No exact version, lock file, package hash, or trusted artifact digest constrains installation. This dependency occupies a particularly sensitive trust boundary: it receives the Garmin email, password, and cached OAuth tokens and performs all remote API communication. Although the audited project contains no evidence that the current dependency is malicious, the open-ended constraint means a future compromised, malicious, or behaviorally incompatible release could be installed without a corresponding review of this Skill. Because Python executes package initialization code during import, a compromised dependency would not need to wait for an explicit API request to run code under the invoking user's account. ### Attack Path 1. An attacker compromises the upstream package publisher, release process, distribution account, or another relevant package-distribution component. 2. The attacker publishes a release satisfying `garminconnect>=0.2.38`. 3. A user or automated Skill installer resolves and installs that release because no upper bound, exact pin, or hash is enforced. 4. `scripts/garmin.py` or `scripts/garmin-pro.py` imports the installed package. 5. Malicious package code executes with the operating-system privileges of the user running the Skill. 6. The package can access credentials supplied to it, cached Garmin tokens, returned health information, and other files available to that user. ### Impact ...[truncated 675 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Pin `garminconnect` to a specifically reviewed version, for example: ```json "pips": ["garminconnect==<reviewed-version>"] ``` 2. Use a lock file containing hashes and install with hash verification, such as: ```bash pip install --require-hashes -r requirements.txt ``` 3. Install dependencies in a dedicated virtual environment under a low-privilege service account. 4. Review the dependency and its transitive dependencies before updating the version pin. 5. Update `README.md` and `SKILL.md` so installation examples use the same pinned, hash-verified dependency policy. 6. Consider generating and reviewing a software bill of materials for release artifacts. ]]>
