AI Security Review

scanned 2d ago · by lpm-firewall-ai

Source inspection resolved the flagged dynamic code generation to vendored WebAssembly runtime support and found no install-time hook or concrete attack behavior. Incident reporting requires an explicit setting and defaults to a local endpoint, so the scanner labels alone do not support blocking this release.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A tool failure triggers reporting only when incident reporting has been enabled in configuration or explicitly through an environment setting.

Impact

If enabled, incident details and tool input are sent to the selected receiver. The inspected default receiver is local.

Mechanism

The reporter sends tool error details, workspace and Git metadata, and the failed tool input to the configured endpoint; the default is localhost.

AI rationale

Evidence

package.jsondist/chunk-IG4Z23CL.jsdist/chunk-IGFN2DM5.js

Network endpoints1

localhost:8000

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json points to the desktop entry and CLI and defines build and prepack scripts, with no npm install lifecycle hook.
The tree-sitter eval builds a function from embedded WebAssembly assembler text in the vendored runtime.
The inspected desktop, CLI, renderer, and utility bundles contain application entry or helper code; the flagged renderer fetch handles module preloads.
Prepared dependency manifests show test or release scripts, and their inspected sources provide terminal styling, CLI parsing, and environment-file loading.
Incident reporting is disabled by default, and its registered caller enables it only through the incidents setting or an explicit environment opt-in.
When enabled after a tool failure, the reporter sends error context, workspace and Git metadata, and tool input to its configured endpoint; the default endpoint is local.

Evidence against

With reporting disabled, the handler returns an allow decision without posting; the default receiver is localhost. This is a gated reporting feature, not an identified attack.
