AI Security Review

scanned 5d ago · by lpm-firewall-ai

The inspected lifecycle path gates broader setup on an explicit environment opt-in, and the menu-bar setup has additional install-condition checks. A clean verdict cannot be established because the required clean-citation set includes a verified binary asset that cannot be cited as UTF-8; the inspected source does not independently establish a warning or attack.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install invokes the package postinstall command; broader bootstrap requires SKS_POSTINSTALL_BOOTSTRAP=1.

Impact

No confirmed attack effect was established from the inspected source.

Mechanism

The guarded bootstrap can install global Codex hooks. A separate menu-bar setup step has platform and installer-condition checks.

AI rationale

Evidence

package.jsondist/cli/install-helpers.jsdist/cli/install-helpers-menubar.jsdist/core/codex-hooks/codex-global-hooks.js

Decision evidence

public snapshot

AI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json defines a postinstall hook that invokes the package CLI.
Postinstall bootstrap returns without running unless SKS_POSTINSTALL_BOOTSTRAP=1 is set.
The earlier menu-bar setup is limited by platform and install conditions; it can also be disabled through environment settings.
Global Codex hook activation writes managed hook configuration, but the reviewed postinstall path gates external mutations behind the opt-in.

Evidence against

The inspected postinstall path does not establish unconsented global Codex hook mutation by default.
No inspected source established credential disclosure, destructive behavior, or remote payload execution.
