- Unpinned Prerelease Third-Party Dependency Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 13–17 **Vulnerability Type**: Unpinned and prerelease-enabled dependency installation **Risk Level**: Medium **Vulnerable Code**: ```markdown > **Note:** This plugin depends on the `mlx-audio` Python library. Ensure it is installed before use: > ```bash > uv tool install mlx-audio --prerelease=allow > ``` ``` ### Technical Analysis The documented installation command retrieves `mlx-audio` from a third-party package registry without specifying an audited version or cryptographic integrity hash. It also explicitly permits prerelease versions. Dependency resolution consequently depends on mutable registry state at installation time. Different users or installation dates may resolve to different package versions, including versions that were never reviewed alongside this Skill. If the package, its publishing account, its build dependencies, or another component in its dependency chain is compromised, installation or subsequent execution could run attacker-controlled code. The project contains only `SKILL.md` and does not include the implementation of the documented `mlx_stt` tool. Therefore, the artifact itself cannot verify the integrity of the installed component or substantiate the claim that all processing remains local. ### Attack Path 1. An attacker compromises the package publisher, a transitive dependency, or another relevant supply-chain component. 2. The attacker publishes a malicious version eligible for resolution by the unpinned command, potentially as a prerelease. 3. A user follows the Skill documentation and runs `uv tool install mlx-audio --prerelease=allow`. 4. The package manager resolves and installs the attacker-controlled release or dependency. 5. Malicious code executes during a source-package build, package invocation, or subsequent transcription operation with the privileges of the user running the tool. 6. That code co ...[truncated 622 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `mlx-audio` to an exact, reviewed release rather than allowing unconstrained resolution. 2. Remove `--prerelease=allow` unless a prerelease is strictly required. If it is required, pin the exact audited prerelease and document why it is necessary. 3. Maintain a lockfile containing exact direct and transitive dependency versions. 4. Require cryptographic hashes for downloaded distributions where the package-management workflow supports them. 5. Document the expected package registry and reject unexpected indexes or alternate dependency sources. 6. Prefer reviewed binary distributions from trusted publishers and carefully assess source distributions and their build backends. 7. Perform dependency vulnerability and provenance checks in CI before updating the approved version. 8. Run the transcription service with least privilege and restrict its filesystem and network access to limit the impact of a compromised dependency. 9. Include or reference a verifiable implementation so reviewers can validate the documented local-only processing claim.
