devez-vibe@1.7.58

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically mutates both Codex and Claude skill directories. It also installs Python dependencies into the user environment and deploys an agent skill that directs local command execution.

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

npm postinstall during package installation.

Impact

A package install changes broad AI-agent control surfaces without an explicit user command and can cause later agent sessions to execute bundled tooling.

Mechanism

Automatic cross-agent skill deployment and user-environment dependency installation.

Policy narrative

When npm installs this package, its postinstall hook copies two bundled skills into both Codex and Claude user skill directories. The copy process also deletes files in those destinations that are not in the package source. The same hook invokes pip to add Python packages to the user environment. One deployed skill then instructs an agent to run local Python commands when web access is blocked. This creates unconsented, persistent cross-agent behavior from an install-time hook.

Rationale

The package has a concrete automatic lifecycle chain that broadly mutates foreign AI-agent control surfaces and the user environment. This meets the install-hook abuse blocking policy regardless of the absence of observed credential exfiltration.

Ai Agent Control Hijack

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