devez-vibe@1.6.53: AI-agent control-surface risk | LPM Firewall

devez-vibe@1.6.53

Stable terminal UI for Codex and Claude Agent SDK

AI Security Review

scanned 22d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall copies the bundled luna-loop skill into the user's Codex and Claude skill directories and prunes extra files there. That mutates foreign AI-agent control surfaces as soon as the package is installed.

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 install of devez-vibe, which runs the postinstall script.

Impact

Codex and Claude pick up a third-party skill and related files in the user skill path without a separate setup command, and extra files in those skill folders can be deleted.

Mechanism

Unconsented postinstall copy of an agent skill into ~/.codex and ~/.claude

Policy narrative

Installing this package runs postinstall, which copies luna-loop into the user's Codex and Claude skill directories and removes leftover files in those folders. Those paths are foreign agent control surfaces, so the skill can be loaded by Codex or Claude without a later setup command. README text describing the copy does not count as consent for an automatic install-time write.

AI rationale

postinstall writes a bundled agent skill into ~/.codex/skills and ~/.claude/skills, which is unconsented mutation of foreign AI-agent control surfaces. That matches a blocking install-time hijack even though the installer does not itself steal secrets.

Ai Agent Control Hijack

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