=3.10" # dependencies = ["spotipy>=2.24.0"] # /// ``` The project documentation explicitly instructs users to execute this script through `uv`, which automatically resolves and installs the declared dependency: ```markdown Python dependencies are managed inline via PEP 723 — `uv run` handles installation automatically. No manual `pip install` needed. ``` ### Technical Analysis The dependency constraint `spotipy>=2.24.0` permits any current or future Spotipy release whose version is at least 2.24.0. The project contains no dependency lockfile, exact version constraint, artifact hash, or upper version bound. As a result, the code executed by this Skill is not limited to the dependency version that existed when the Skill was audited. Python packages can execute code during import, and `spotipy` is imported at module initialization. A compromised or malicious future release satisfying this constraint could therefore run code with the privileges of the user invoking the Skill. This is a supply-chain weakness rather than evidence that the current Spotipy package is malicious. ### Attack Path 1. An attacker compromises the upstream Spotipy publishing account, package repository, or release process and publishes a malicious version satisfying `>=2.24.0`. 2. A user invokes a documented command such as: ```bash uv run scripts/spotify.py devices ``` 3. In an environment without a previously fixed resolution, `uv` resolves and installs the attacker-controlled compatible release. 4. Python imports `spotipy` before processing the requested command. 5. Malicious package initialization code executes with the invoking user's operating-system privileges. 6. That code may read the Spotify client credentials from the environmen ...[truncated 890 chars]- Remediation
