SKILL.md:62
Vulnerability Type: Insecure third-party dependency installation
Risk Level: MediumComplete Code Snippet:
bash # Install yt-dlp (video download) pip3 install --break-system-packages yt-dlpTechnical Analysis
The documented setup command installs the latest available
yt-dlprelease without pinning a reviewed version or verifying an integrity hash. Package resolution is therefore mutable: running the same command at different times may install different code from the configured Python package index.The
--break-system-packagesoption also disables the protection applied to externally managed Python environments. This allowspipto alter packages associated with the host's system-managed Python installation, increasing the potential for dependency conflicts and damage to applications that share that environment.Exploitation depends on compromise or manipulation of the package supply chain, such as a compromised upstream release, package-index account, index configuration, or network/package mirror. There is no evidence in the audited file that
yt-dlpitself is malicious; the finding concerns the unsafe installation procedure.Attack Path
- An attacker compromises a future
yt-dlprelease or a package source used by the environment. - An operator follows the documented command.
pipresolves the mutable latest release without checking a pinned version or expected hash.- Package-controlled installation or runtime code executes with the permissions of the user running
pip. - Because system-package protection was explicitly bypassed, the installation may also modify or conflict with the system-managed Python environment.
Impact Assessment
A successful supply-chain compromise could execute arbitrary code with the installing user's privileges. It could access data and credentials available to that user, alter use ...[truncated 278 chars]

Remediation Suggestions
- Remove
--break-system-packages. - Install the dependency in an isolated virtual environment or through
pipx. - Pin
yt-dlpto a specifically reviewed version rather than installing the mutable latest release. - Use hash verification through a locked requirements file, for example
pip install --require-hashes -r requirements.txt. - Review and deliberately update the pinned version on a controlled schedule.
- Run dependency installation and video processing as an unprivileged user in a constrained environment.
- Prefer a trusted internal package mirror with provenance, integrity, and release-approval controls where available.
A hardened installation pattern is:
bash python3 -m venv .venv . .venv/bin/activate python3 -m pip install --require-hashes -r requirements.txtThe requirements file should contain an approved exact version and its expected distribution hashes.
- Remove
