- Unpinned Third-Party Dependencies Create a Supply-Chain Risk## Vulnerability Details **File Location**: `SKILL.md:11-14` **Vulnerability Type**: Unpinned and integrity-unverified Python dependencies **Risk Level**: Medium **Vulnerable Code:** ```markdown ## Dependencies ```bash pip3 install tinytuya tuya-connector-python ``` ``` ### Technical Analysis The installation instructions retrieve the latest available versions of `tinytuya`, `tuya-connector-python`, and their transitive dependencies from pip's configured package index. No exact versions, cryptographic hashes, lockfile, or trusted index configuration is provided. Consequently, the code installed by this command can change after the Skill has been reviewed. A compromised package maintainer account, malicious replacement release, dependency confusion condition, compromised transitive dependency, or compromised package index could cause arbitrary attacker-controlled Python code to be installed or imported. The audit found no evidence that the currently named packages are malicious. The vulnerability is the absence of version and integrity controls around executable third-party dependencies. ### Attack Path 1. An attacker compromises one of the named packages, a transitive dependency, a maintainer account, or an applicable package index. 2. The attacker publishes a malicious release that satisfies the unrestricted dependency request. 3. A user follows the documented `pip3 install` command. 4. pip resolves and downloads the attacker-controlled release. 5. Malicious code executes during package installation or when `tuya_control.py` or `tuya_scan.py` imports the package. 6. The malicious dependency operates with the privileges and environment access of the user running pip or the Skill. ### Impact Assessment Successful exploitation could provide arbitrary code execution under the installing or executing user's account. Depending on that account's privileges, the attacker could access local files, environment varia ...[truncated 403 chars]
- Remediation
- ## Remediation Suggestions 1. Provide a reviewed dependency lockfile containing exact versions for all direct and transitive dependencies. 2. Require cryptographic hashes, for example through a generated `requirements.txt` used with: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 3. Install dependencies in a dedicated, non-privileged virtual environment rather than globally or as root. 4. Configure an explicitly trusted package index or an internally controlled package mirror. 5. Add automated dependency vulnerability, provenance, and update review checks. 6. Test and review dependency upgrades before changing pinned versions. 7. Document the supported Python and package versions to make installations reproducible.
