Runtime-neutral HTTP layer for the Agent Architecture Board: the Hono controllers, middleware (auth/authz/CORS/error), request helpers and the gateway seams shared by every deployment facade (Cloudflare Worker, Node service).

AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The package is a runtime-neutral HTTP server layer with user-invoked controllers and provider integrations.

Static reason

One or more suspicious static signals were detected.

Trigger

Importing exports or invoking configured Hono routes in an application server.

Impact

Expected backend behavior when configured by the host application; no covert credential theft or install-time behavior identified.

Mechanism

Feature-aligned HTTP routing, OAuth token exchange, GitHub API calls, LLM/web-search proxying, and persistence RPC.

Rationale

Static inspection shows package-aligned server, OAuth, GitHub, search, crypto, and persistence code with no lifecycle execution or covert exfiltration behavior. Scanner hints are explained by documented PEM parsing helpers, dynamic Proxy repository dispatch, and expected network integrations.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for block

Network-capable HTTP/OAuth server code exists but appears feature-aligned, not covert.
Credential handling is present for OAuth, GitHub App, runner, and personal secrets, but no harvesting/exfiltration path was found.

Evidence against

package.json has no lifecycle hooks or bin; main only exports dist/index.js.
dist/index.js is a barrel export for HTTP controllers, auth, crypto helpers, GitHub, persistence, and agents.
dist/crypto/encoding.d.ts contains PEM marker documentation only; no embedded private key or secret value.
dist/modules/tasks/TaskSourceController.js defines Hono task-source/OAuth routes gated through container services and signed state.
Network endpoints inspected are expected providers: GitHub, Google, Linear, Brave Search, SearXNG/configured base URLs, and internal persistence RPC.
No child_process, install-time execution, destructive persistence, prompt/reviewer manipulation, or AI-agent control-surface writes found.
