AI Security Review
scanned 3h ago · by lpm-firewall-aiNo confirmed malicious payload was found in package source. The remaining risk is an install-time lifecycle hook invoking npx for package sorting, which can execute a third-party tool during installation.
Static reason
One or more suspicious static signals were detected.
Trigger
npm install runs package postinstall
Impact
Potential install-time execution of sort-package-json and possible package.json formatting in the installed package directory; no exfiltration or persistence shown.
Mechanism
install-time npx tool execution
Rationale
Static inspection found benign runtime component code, but the package does execute an npx-based formatting command during postinstall. This supports a warning rather than a publish block because no concrete malicious payload or exfiltration path was present in the package files.
Evidence
package.jsonsrc/index.jssrc/define/blockquote-dialog.jssrc/BlockquoteDialog.jssrc/styles/blockquote-dialog-styles.css.jssrc/styles/blockqoute-dialog-animations-styles.css.js
Decision evidence
public snapshotAI called this Suspicious at 78.0% 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 at install time
- npx may execute/fetch a tool not listed as a dependency
Evidence against
- src/index.js only re-exports BlockquoteDialog
- src/define/blockquote-dialog.js only registers the custom element
- src/BlockquoteDialog.js implements Lit dialog UI behavior
- No credential/env harvesting, shell APIs, eval, filesystem APIs, or exfiltration endpoints found in source
- Style files only export Lit CSS
