devez-vibe@1.8.13

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The postinstall hook performs unconsented agent-skill deployment and package installation. The mutation is limited to the package's own named skills and no concrete exfiltration or self-dependency chain was found, so this warrants a warning rather than 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 during package installation.

Impact

It can alter available Codex and Claude agent behavior without an explicit setup command and expands local execution and network-capable tooling.

Mechanism

Automatic agent-skill deployment and user-level pip installation.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Its postinstall hook automatically runs two setup scripts.
The installer targets both Codex and Claude user skill roots.
The installer copies and prunes bundled skills without a user command.
Postinstall automatically invokes pip with a user-level install.
A bundled skill provides WAF-bypass and browser-automation capability.

Evidence against

The manifest has no dependency on another release of itself.
The installer is limited to its two named bundled skill directories.
No direct credential exfiltration or hard-coded outbound endpoint was found in the inspected launcher and bridge source.
