AI Security Review

scanned 3h ago · by lpm-firewall-ai

No confirmed malicious payload is present in package source. The residual risk is an install-time lifecycle hook invoking npx sort-package-json, which may execute tooling during npm install.

Static reason
One or more suspicious static signals were detected.
Trigger
npm install postinstall lifecycle
Impact
Potential install-time execution of sort-package-json tooling; no observed exfiltration, persistence, destructive behavior, or runtime attack code.
Mechanism
install-time npx formatter invocation
Rationale
The package is not confirmed malicious, but an install-time npx invocation is unnecessary for a published library and creates avoidable execution risk. Runtime source is benign and package-aligned, so this should warn rather than block.
Evidence
package.jsonsrc/index.jssrc/BlockquoteBaseMeta.js

Decision evidence

public snapshot
AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
  • package.json defines postinstall: npm run sort:package
  • sort:package runs npx sort-package-json during install
  • npx can execute/download tooling at install time if unavailable
Evidence against
  • src/index.js only re-exports BlockquoteBaseMeta
  • src/BlockquoteBaseMeta.js implements in-memory Map-backed metadata storage
  • No child_process, fs, eval, dynamic import, credential access, or runtime network calls in src
  • Only URLs found in source are documentation/comment links
Behavioral surface
SourceNo risky source behavior triggered.
Supply chainNo supply-chain packaging signals triggered.
ManifestNo manifest risk signals triggered.
