@cat-factory/server@0.78.0

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 10h ago · by lpm-firewall-ai

No confirmed malicious attack surface was found. The package is a runtime HTTP/server library with authenticated controller routes and package-aligned outbound integrations.

Static reason

One or more suspicious static signals were detected.

Trigger

Consumer imports or deploys the server package and invokes its HTTP routes.

Impact

Package-aligned GitHub/OAuth/LLM/search integration traffic; no install-time execution, persistence, credential harvesting, or exfiltration found.

Mechanism

Hono controllers and fetch-based provider clients

Rationale

Static inspection found suspicious primitives only in expected server-side integration code, with no lifecycle hook, hidden payload, agent control-surface mutation, filesystem persistence, or unconsented execution path. Scanner secret/dynamic-require hints were noisy: the cited files are PEM helper declarations/comments and ordinary Hono task routes.

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no preinstall/install/postinstall lifecycle hooks and exports only ./dist/index.js
dist/index.js is an export barrel for Hono controllers, auth, GitHub, persistence, and agent server helpers
dist/modules/tasks/TaskSourceController.js contains route handlers and service calls, not dynamic require/import behavior
dist/crypto/encoding.js and .d.ts contain PEM parsing helpers/comments, not embedded private keys or secrets
rg found no child_process, eval/new Function, dynamic import/require, native binary loading, or filesystem write APIs in dist JS
Outbound fetch use is runtime route/provider behavior with auth, budget checks, or SSRF guards for configured local/search endpoints
