@sentropic/h2a-runtime@0.93.3
h2a heavy runtime (sessions / k8s / tunnel, node-pty + aws-sdk). Lazily imported by @sentropic/h2a; installed separately.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe source supports high-impact credential and AI-agent configuration operations, but they are command-driven and package-aligned rather than covert install-time behavior. No concrete malicious chain was established.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs h2a remote-session, gateway, or `plugin add` commands.
Impact
A user-selected remote endpoint or plugin can receive credentials or gain configured agent execution access.
Mechanism
credential forwarding and explicit MCP configuration

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- User-invoked remote-session flows collect Codex, Claude, and Gemini credential/config files for pod transfer.
- Explicit `plugin add` installs a selected package and registers its MCP entry in Claude, Codex, and Gemini user configuration.
- A fixed LLM gateway URL is present, creating a credential-routing capability when that feature is invoked.
Evidence against
- package.json has no lifecycle scripts.
- The main module runs CLI dispatch only when it is the direct entry point.
- Remote endpoint persistence requires an explicit config-set command; no fixed remote control-plane endpoint was found.

Source & flagged code
6 flaggeddist/index.jsView file
•Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
dist/index.js:
import { existsSync, mkdirSync, readdirSync, readFileSync, realpathSync, statSync, writeFileSync, } from "node:fs";
import { createInterface } from "node:readline";
baseUrl: opts.remote,
async function refreshProfileSession(baseUrl, sessionId, opts) {
const remoteProfile = (await getRemoteSession(baseUrl, sessionId)).session
const response = await refreshRemoteSession(baseUrl, sessionId, credentials, fetch, opts.name);

process.stderr.write(`[h2a] sending creds for ${sent.join(", ")} to ${baseUrl}/sessions/${sessionId}: ${Object.keys(merged).join(", ")}\n`);

Credential Redirect Persistence
Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection.
