AI Security Review
scanned 1mo ago · by lpm-firewall-aiChromatic 18.9.5 is the published visual-testing CLI: it has no npm lifecycle scripts and contacts its own index only when the user runs it. Bundled eval and child-process usage sit in library and git/build helpers and do not form a hidden install chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
No install or import trigger starts unsolicited behavior; network calls start when a user runs the chromatic binary or the node run/share API.
Impact
No unconsented credential theft, persistence, destructive action, or foreign agent-control write was found.
Mechanism
The CLI loads dotenv from the local process and sends project or user tokens only to the configured Chromatic index URL, defaulting to the vendor host.
AI rationale
Chromatic 18.9.5 is the published visual-testing CLI: it has no npm lifecycle scripts and contacts its own index only when the user runs it. Bundled eval and child-process usage sit in library and git/build helpers and do not form a hidden install chain.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines the chromatic CLI bins and a single runtime dependency on semver, with no preinstall, install, or postinstall scripts.
- The programmatic entry talks to the operator Chromatic index over GraphQL and bearer-authenticated API calls only after the CLI or node API is invoked.
- dist/v1-BB-RtEBW.cjs is a bundled support module required by the CLI implementation, not an install-time payload.
Evidence against
- eval and Function constructors appear inside minified library code such as observable and YAML helpers, not as an install hook or hidden downloader.
- Optional peer dependencies are other Chromatic test integrations and are not installed automatically.
