- Unpinned Third-Party Python Dependency<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md`, lines 7-10 **Vulnerability Type**: Unpinned third-party dependency **Risk Level**: Medium ### Vulnerable Code ```yaml requires: bins: [python3] env: [MINIMAX_API_KEY] pip: [requests] ``` ### Technical Analysis The Skill declares `requests` without a fixed version or integrity hash. As a result, installation may resolve to a different package version over time. If the package distribution channel or a future release is compromised, installation could introduce attacker-controlled code even though the reviewed Skill source remains unchanged. The dependency name is legitimate and no malicious package source, dependency confusion namespace, or typosquatting was identified. The risk arises from mutable dependency resolution rather than confirmed malicious behavior in the current package. ### Attack Path 1. An operator or automated Skill installer processes the `pip: [requests]` dependency declaration. 2. The package manager resolves the dependency from its configured package index without enforcing a reviewed version or cryptographic hash. 3. An attacker compromises the package index, distribution account, installation environment, or a future dependency release. 4. The installer downloads the compromised package or one of its transitive dependencies. 5. Attacker-controlled package installation or runtime code executes with the privileges of the user or Agent installing or invoking the Skill. 6. That code could access data available to the process, including the `MINIMAX_API_KEY`, user-provided TTS text, generated files, and other resources permitted to the host account. ### Impact Assessment Successful exploitation could result in arbitrary code execution within the privileges of the installing or executing account. The affected scope could include environment variables, local files accessible to that account, network access available to the process, and TTS input content. No evidenc ...[truncated 569 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Pin `requests` to a specifically reviewed version instead of allowing unrestricted resolution, for example: ```yaml pip: [requests==<reviewed-version>] ``` 2. Use a lock file or requirements file that also pins all transitive dependencies. 3. Require cryptographic hashes during installation, such as pip's `--require-hashes` mode with SHA-256 hashes for every resolved package. 4. Install packages only from an explicitly trusted package index using TLS, and prevent fallback to untrusted or user-controlled indexes. 5. Run dependency vulnerability and provenance checks in CI before publishing the Skill. 6. Periodically update the pinned versions through a controlled review process rather than accepting automatic mutable upgrades. 7. Where supported, install and execute the Skill in an isolated environment with access limited to the required API credential, destination domains, input text, and output directory. ]]>
