@vibelet/cli@1.2.184

Cross-platform CLI for installing and running the Vibelet daemon

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is not an install-hook attack because the manifest has no lifecycle scripts. The agent-session access, trust-state mutation, remote pairing, and persistence warrant a warning-level block decision rather than clean classification.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the vibelet command, especially its Claude or Codex takeover commands.

Impact

A paired remote client could gain control over sensitive AI-agent sessions; trust prompts may be bypassed.

Mechanism

Persistent agent-session control with trust-state mutation and remote pairing.

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The obfuscated daemon enumerates Codex session and archived-session directories.
The daemon writes project records that mark trust dialogs and onboarding as accepted.
The CLI enables remote access by default and offers Claude and Codex app takeover.
It installs a persistent user service or detached daemon after an explicit CLI start.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
The executable is a bin command, so the daemon path requires an explicit user invocation.
The visible detached network check targets the npm registry for version metadata.
