= 2024.01.01, gallery-dl >= 1.26.0 (optional, for image posts) ## Prerequisites ```bash # macOS brew install yt-dlp gallery-dl # pip pip install yt-dlp gallery-dl # Verify yt-dlp --version && gallery-dl --version ``` ``` ### Technical Analysis The installation commands retrieve the latest available releases of `yt-dlp`, `gallery-dl`, and their transitive dependencies from the package repositories configured on the user's system. Although the documentation states minimum versions, it does not enforce exact reviewed versions, use a lockfile, verify package hashes or signatures, or identify trusted package sources. Checking `--version` only confirms that executables are available; it does not verify their integrity or provenance. Package installation can execute package-controlled installation logic. Consequently, a compromised package repository, malicious mirror, dependency compromise, or unsafe local package-manager configuration could introduce code that was not present when this Skill was reviewed. ### Attack Path 1. An attacker compromises a relevant package, transitive dependency, package index, mirror, or package-manager configuration. 2. A user follows the Skill documentation and runs `brew install yt-dlp gallery-dl` or `pip install yt-dlp gallery-dl`. 3. The package manager retrieves an attacker-controlled or compromised release because no exact versions or hashes are enforced. 4. Package installation logic or the installed executable runs with the privileges of the invoking user. 5. The malicious component accesses data available to that user, performs unauthorized network activity, or alters local files. ### Impact Assessment Successful exploitation could provide arbitrary code execution with the privileges of ...[truncated 338 chars]- Remediation
