- Unpinned Third-Party Package Installation<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md`, line 23 **Vulnerability Type**: Supply-chain exposure through an unpinned dependency **Risk Level**: Medium ### Vulnerable Code ```bash pip install yt-dlp ``` ### Technical Analysis The setup instructions install `yt-dlp` without a version constraint or integrity hash. Consequently, the package and its transitive dependencies may change after this Skill has been reviewed. A future compromised, malicious, or otherwise unsafe package release could execute installation-time or runtime code with the privileges of the user following these instructions. The instruction does not itself establish that the current `yt-dlp` package is malicious. The vulnerability is the absence of reproducible dependency controls, which prevents users from reliably installing the same reviewed artifact. ### Attack Path 1. An attacker compromises a future `yt-dlp` release, one of its dependencies, or the package-distribution channel. 2. A user follows the Skill's setup instructions and runs `pip install yt-dlp`. 3. `pip` resolves and downloads the latest available mutable package set rather than a previously reviewed version. 4. Malicious package code executes during installation or when the Skill later invokes `yt-dlp`. 5. The code operates with the installing or invoking user's privileges and can access resources available to that account. ### Impact Assessment Successful exploitation could result in arbitrary code execution under the affected user's account. The accessible scope may include the user's files, environment variables such as `GROQ_API_KEY`, browser-exported cookie files supplied to the workflow, and network resources available to the process. This instruction does not directly request elevated privileges for the Python package, so the default impact is limited to the privileges of the user running `pip` or `yt-dlp`. ]]>
- Remediation
- <![CDATA[ ## Remediation Suggestions - Pin `yt-dlp` to a specifically reviewed version instead of installing the latest release: ```bash python3 -m pip install "yt-dlp==<reviewed-version>" ``` - Publish a lock file or requirements file containing cryptographic hashes, and install with hash verification: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` - Review and update pinned versions through a controlled dependency-update process. - Install the package in a dedicated virtual environment rather than the global Python environment. - Prefer a trusted operating-system package or a verified standalone release when an appropriate integrity-validation mechanism is available. - Avoid running the installation or media-processing pipeline as root. ]]>
