- Finding
- Unpinned Package Execution Through npx## Vulnerability Details **File Location**: `README.md:41-45` **Vulnerability Type**: Unpinned third-party package execution **Risk Level**: Medium ### Vulnerable Code ```bash npx clawhub install ai-news-briefing ``` ### Technical Analysis The documented installation procedure invokes `clawhub` through `npx` without specifying a reviewed package version or integrity value. If the package is not already available locally, `npx` can retrieve the current package release from the configured npm registry and execute it with the invoking user's privileges. Consequently, the code executed by this command can change after this skill has been reviewed. Compromise of the package publisher, npm account, registry, or a future `clawhub` release could turn the documented installation command into a supply-chain execution vector. No evidence establishes that the current `clawhub` package is malicious. The vulnerability is the unsafe, unpinned trust relationship created by the documented command. ### Attack Path 1. An attacker compromises the `clawhub` package, its publisher account, its distribution infrastructure, or a future package release. 2. The attacker publishes a release containing malicious package code or lifecycle behavior. 3. A user follows the installation command in `README.md`. 4. `npx` resolves and downloads the attacker-controlled current version because no version or integrity constraint is supplied. 5. The downloaded package executes under the user's account during installation. 6. The payload can perform actions permitted to that user before or while installing the skill. ### Impact Assessment Successful exploitation could provide arbitrary code execution with the privileges of the user running the installation command. Depending on that user's permissions and environment, the payload could access user-readable files, environment variables, development credentials, project data, and network resources, or mod ...[truncated 305 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `clawhub` to a specific, reviewed version, for example: ```bash npx --yes clawhub@<reviewed-version> install ai-news-briefing ``` 2. Verify the selected release's provenance and integrity before recommending it. 3. Use a lockfile and registry-provided integrity metadata when installation is managed through a package manifest. 4. Document the expected trusted registry and avoid silently accepting packages from alternate registry configurations. 5. Prefer installing a verified CLI release separately and invoking the locally pinned binary rather than downloading and executing the latest release in one step. 6. Review new versions before updating the pinned version and perform installation using a least-privileged account in an isolated environment.
