- Unpinned External Go Dependency Uses a Mutable Latest Version## Vulnerability Details **File Location**: `SKILL.md`, lines 9-16 **Vulnerability Type**: Supply-chain risk caused by an unpinned executable dependency **Risk Level**: Medium **Vulnerable Code:** ```json "install": [ { "id": "go", "kind": "go", "module": "github.com/steipete/sonoscli/cmd/sonos@latest", "bins": ["sonos"], "label": "Install sonoscli (go)", }, ], ``` ### Technical Analysis The installation configuration retrieves `github.com/steipete/sonoscli/cmd/sonos@latest`. The `latest` selector is mutable and does not identify a specific reviewed release or commit. Consequently, the source code installed in the future may differ from the code that existed when this Skill was audited. This creates a dependency supply-chain exposure. If the upstream repository, maintainer account, release process, or one of the resolved dependencies is compromised, a malicious version may be selected by subsequent installations. Although retrieving and compiling ordinary Go source does not inherently execute that application during compilation, the resulting unreviewed `sonos` executable will run when the Skill invokes it. ### Attack Path 1. An attacker compromises the upstream repository, a maintainer account, or the relevant release workflow. 2. The attacker publishes or causes resolution to a malicious version of the `sonos` command. 3. A user installs the Skill after the malicious version becomes the version selected by `@latest`. 4. The installation process retrieves and builds the attacker-controlled source instead of a previously reviewed version. 5. The Skill or user subsequently invokes the installed `sonos` executable. 6. The malicious executable performs actions with the permissions and environmental access of the invoking process. ### Impact Assessment Successful exploitation would provide code execution under the account running the installed `sonos` binary.

- Remediation
- ## Remediation Suggestions 1. Replace `@latest` with a specific, reviewed semantic version, for example: ```json "module": "github.com/steipete/sonoscli/cmd/sonos@vX.Y.Z" ``` 2. For stronger immutability, pin the dependency to a reviewed commit where supported by the installation framework. 3. Record and verify expected source, module, or artifact checksums before installation. 4. Prefer signed releases and verify available provenance or build attestations. 5. Review the pinned release and its transitive Go dependencies before updating it. 6. Perform dependency updates through a controlled process that includes source review, security scanning, and functional testing. 7. Run the CLI with least privilege and limit filesystem, credential, environment-variable, and local-network access to what Sonos control strictly requires.
