devez-vibe@1.7.91

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package performs unconsented postinstall mutation of first-party AI-agent extension directories and user-wide dependency installation. This is a concrete lifecycle risk, but the inspected source does not establish the stronger malicious chain required for a block.

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

Impact

User agent behavior and Python environment are changed without an explicit setup command.

Mechanism

Automatic AI skill deployment and user-wide pip dependency installation

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Its postinstall hook automatically installs packaged skills and prepares dependencies.
The installer writes both skills into the user's Codex and Claude skill directories and removes files absent from the package copy.
The postinstall hook invokes pip with user-wide installation and upgrade options.
The CLI can execute an absolute executable path obtained from a local pointer file.
The shipped skill content gives operational instructions to AI agents, expanding the effect of the automatic skill installation.

Evidence against

The installer targets only two package-owned skill directories rather than arbitrary agent settings.
The inspected lifecycle scripts do not read or transmit credentials.
No concrete secret exfiltration, destructive project action, or remote payload download was found in the inspected JavaScript source.

Ai Agent Control Hijack

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