- Unpinned Third-Party Package Installation## Vulnerability Details **File Location**: `SKILL.md`, line 22 **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Medium **Vulnerable Code Snippet**: ```bash pip3 install yt-dlp ``` ### Technical Analysis The installation command does not pin `yt-dlp` to a reviewed version or verify its integrity with a cryptographic hash. Consequently, the installed code may differ over time from the version considered during this audit. Because Python package installation can invoke package-controlled build or installation logic, compromise of the package, one of its dependencies, the configured package index, or a future release could result in arbitrary local code execution. This finding concerns mutable supply-chain trust; the audit found no evidence that `yt-dlp` itself is currently malicious. ### Attack Path 1. An attacker compromises a future `yt-dlp` release, a transitive dependency, or the package index used by the victim. 2. A user follows the prerequisite and executes `pip3 install yt-dlp`. 3. `pip` resolves and downloads the attacker-controlled package content because no reviewed version or hash is required. 4. Malicious build, installation, or runtime code executes in the user's environment. 5. The payload obtains the permissions of the account running the command and can access resources available to that account. ### Impact Assessment Successful exploitation could provide arbitrary code execution with the privileges of the installing or invoking user. Depending on that user's permissions, the attacker could read or modify accessible files, steal browser cookies or other credentials available to the process, alter downloaded media, or establish additional malicious behavior. The direct scope is the host and user environment where the dependency is installed; this instruction does not itself request elevated privileges.
- Remediation
- ## Remediation Suggestions - Pin `yt-dlp` to a specifically reviewed version rather than installing the latest available release. - Maintain the dependency in a locked requirements file and verify it using trusted hashes, for example: ```text yt-dlp==REVIEWED_VERSION --hash=sha256:VERIFIED_DISTRIBUTION_HASH ``` Install it with: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` - Obtain the verified hash from an approved artifact repository or independently validated release artifact. - Use an organization-controlled package mirror where possible and restrict fallback to untrusted indexes. - Periodically review and deliberately update the pinned version after checking release provenance and security advisories. - Install the package in an isolated virtual environment under a non-privileged account.
