devez-vibe@1.6.64: AI-agent control-surface risk | LPM Firewall

devez-vibe@1.6.64

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 25d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A postinstall hook places and synchronizes a package-controlled skill in global Codex and Claude directories. The installed skill governs agent delegation and CLI execution; the bridge also prefers bypass-permissions mode.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

Installing the package runs postinstall.

Impact

It mutates broad AI-agent control surfaces without a user setup command and can influence later agent behavior.

Mechanism

Automatic cross-agent skill installation with recursive synchronization and permission-bypass preference.

Policy narrative

On npm installation, postinstall runs a script that copies a bundled skill into both the user's Codex and Claude global skill directories and removes target files no longer in the package. The skill instructs agents to use a specific delegated model and execute Codex CLI workflows. Separately, the bundled Claude bridge attempts bypass-permissions mode. This is unconsented install-time mutation of broad AI-agent control surfaces.

AI rationale

The package has a concrete automatic install-time chain that alters two foreign global agent configurations and installs instructions controlling later agent actions. This meets the install-control-surface block policy.

Ai Agent Control Hijack

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