AI Security Review

scanned 15d ago · by lpm-firewall-ai

The global postinstall automatically configures a package-owned CLI by changing PATH ordering and adding schedules, so this merits a warning. The inspected code does not establish a concrete malicious attack or broad foreign agent control-surface mutation.

Static reason

One or more suspicious static signals were detected.

Trigger

Installing globally with npm on a supported platform, unless postinstall is skipped or CI is detected.

Impact

Commands resolved through PATH may use the package's shims; no separate malicious action was confirmed in the inspected source.

Mechanism

Postinstall runs the package's installer, which changes shell startup PATH blocks and installs package-owned schedules.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs a postinstall script.
Postinstall skips local installs and runs automatically only for global installs, unless disabled or running in CI.
The installer prepends its own directory to PATH so its shims take precedence.
The installer appends PATH changes to shell startup files and can install scheduled jobs.

Evidence against

The postinstall invokes the package's own installer; the inspected source shows no foreign agent configuration write or remote payload execution.
The selector CLI reads JSON from standard input and writes a JSON response to standard output.

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.
