devez-vibe@1.6.58: AI-agent control-surface risk | LPM Firewall

devez-vibe@1.6.58

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 23d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. The postinstall hook silently installs a package-controlled skill into the user-level Codex and Claude control surfaces. It also prunes files from those installed skill directories.

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 npm package.

Impact

Future agent sessions can load the package-controlled skill and follow its delegated-agent and command instructions.

Mechanism

Postinstall mutation of external AI-agent skill directories.

Policy narrative

npm installation runs install-skills.mjs without an explicit setup command. The script writes the bundled luna-loop skill into both Codex and Claude user directories and deletes destination entries absent from the package. The installed skill contains instructions to invoke Codex and create delegated agents, creating a package-controlled instruction channel in two unrelated AI-agent profiles.

AI rationale

This is an unconsented postinstall mutation of broad, foreign AI-agent control surfaces, with deletion capability. The lifecycle payload is executable agent instruction content rather than package-owned application setup.

Critical

Ai Agent Control Hijack

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

The installer copies and prunes a payload in both Codex and Claude user skill directories.
