AI Security Review

scanned 11d ago · by lpm-firewall-ai

The package automatically installs its bundled agent skill during postinstall, which is a guarded, package-owned extension setup capability. The inspected OAuth code uses loopback callbacks and sends credentials to the configured service base URL.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package through npm, unless the hook is skipped by its environment checks.

Impact

The package can add its own skill instructions to an AI agent's available skills; no broader control-surface mutation or active attack was established.

Mechanism

The hook invokes the skill installer, which copies package-bundled skill files to the default Codex skills location or a configured directory.

AI rationale

Evidence

package.jsonscripts/postinstall.mjsdist/skill/skill-manager.js~/.codex/skills

Decision evidence

public snapshot

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

Evidence for warning

The package runs a postinstall hook that can automatically install bundled skills.
The default skill destination is the user's Codex skills directory.
The installer skips unmanaged or modified existing skills unless forced, limiting overwrite risk.
Google and MemHub authentication use user-initiated login flows and loopback callbacks.

Evidence against

No credential theft, unrelated data exfiltration, or remote payload execution was identified in the inspected authentication code.

Ai Agent Control Hijack

Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.
