claude-multiacc@2.0.44

Unified Claude Code and OpenAI Codex subscription pooling with quota-aware selection.

AI Security Review

scanned 15d ago · by lpm-firewall-ai

The install-time behavior is gated to global installs and implements this package’s command-shim setup, a lifecycle risk that warrants a warning. Inspected source did not establish payload execution, credential exfiltration, or other concrete attack behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

Global npm installation, unless CI or the explicit skip flag applies.

Impact

Claude and Codex commands can be routed through the package’s account manager, and scheduled maintenance may run.

Mechanism

Postinstall invokes install.sh, which configures PATH and scheduled jobs for the package’s command shims.

AI rationale

Evidence

package.jsonscripts/postinstall.mjsinstall.shlib/install_actions.sh

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs a postinstall script.
The postinstall proceeds only for global installs, skips CI and supports an explicit skip flag, then runs install.sh.
The installer places its shim first in PATH to route Claude and Codex commands through the account manager.
The test finding’s base64 sample is a one-byte image fixture used in test data.
The launcher identifies itself as an account-pool manager.

Evidence against

The postinstall has global-install and CI gates, and reports manual setup if installation fails.
The inspected test sample is ordinary fixture data; no payload behavior was established from it.

2// Runs after `npm install`. On a GLOBAL install/update it wires the addon up by

3// running install.sh (idempotent), so `npm i -g claude-multiacc@latest` fully updates

4// the shim, CLI, and scheduled jobs with no extra step. Deliberately best-effort:

5// npm's own CI, sandboxes, and non-global/dev installs must never be broken by it, and

6// a failed install.sh must not fail `npm install` — it only prints how to finish by hand.
