- Unpinned Third-Party Python Dependency Installation## Vulnerability Details **File Location**: `tools.md`, lines 95-98 **Vulnerability Type**: Unpinned dependency and insufficient supply-chain verification **Risk Level**: Medium **Vulnerable Code Snippet**: ```markdown ### Bleak (Python) — Recommended ```bash pip install bleak ``` ``` ### Technical Analysis The Skill recommends installing `bleak` directly from the package index without specifying an exact version, verifying package hashes, using a lockfile, or documenting the expected source and publisher. The installed code can therefore change independently of the reviewed Skill. Although no malicious package or dependency is embedded in the project, following this instruction resolves and installs whichever release is selected at installation time. A compromised publisher account, malicious upstream release, or compromised transitive dependency could introduce arbitrary package code. Depending on the package format and installer behavior, attacker-controlled code could execute during installation or when the Agent later imports and uses the library. ### Attack Path 1. An attacker compromises the upstream package publisher, distribution channel, or a transitive dependency. 2. The attacker publishes a malicious version that remains compatible with the unrestricted package name. 3. A user or Agent follows the documented `pip install bleak` instruction. 4. The package installer resolves the malicious or compromised release because no trusted version or hash is enforced. 5. Malicious code executes during installation or when the Bluetooth library is imported. 6. The code operates with the privileges of the user running `pip` or the consuming Agent process. ### Impact Assessment Successful exploitation could provide arbitrary code execution with the installing user's privileges. This may permit access to files available to that account, including Bluetooth profiles, device identifiers, interaction history, packet ...[truncated 343 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `bleak` to a specifically reviewed version rather than installing an unrestricted latest release. 2. Use a lockfile or requirements file containing cryptographic hashes, and install with hash enforcement. 3. Document the expected official package index, project URL, and publisher so users can validate package provenance. 4. Install the dependency in an isolated virtual environment instead of the global Python environment. 5. Review and pin transitive dependencies where practical. 6. Incorporate dependency vulnerability and integrity scanning into the release process. 7. Update pinned versions through an explicit review process rather than allowing silent upstream changes.
