claude-multiacc@2.0.37

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

AI Security Review

scanned 15d ago · by lpm-firewall-ai

The postinstall hook automatically invokes installer behavior for global non-CI installs, and that behavior changes command routing through PATH. The source supports a warning for guarded package-owned CLI setup, but does not establish a concrete attack requiring a block.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

A non-CI global npm installation, unless postinstall is explicitly skipped.

Impact

Future Claude and Codex command invocations can be routed through the package's account-selection shims.

Mechanism

The postinstall hook runs install.sh, whose installer adds the package bin directory at the front of PATH in shell configuration.

AI rationale

Evidence

scripts/postinstall.mjslib/install_actions.shshell configuration files

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs only for a global, non-CI install unless explicitly skipped, then launches the package's installer.
The installer adds its bin directory to the front of PATH in shell configuration, routing Claude and Codex commands through package shims.
The test source confirms the installer writes a marked PATH block; this is a real install-time configuration change.

Evidence against

The automatic setup is gated to global installs and can be skipped with an environment variable.
The inspected Codex shim describes itself as a PATH shim and locates and executes the real Codex binary; no unrelated network endpoint or payload execution was identified in the inspected excerpt.
