negotium@0.6.1

Install the Negotium multi-agent runtime and CLI with one package

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No unconsented install-time foreign AI-agent mutation or credential exfiltration was confirmed, so a block is not warranted. The runtime session/control-context rewriting is nevertheless a concrete, high-risk capability requiring a warning.

Static reason

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

Trigger

User runs a Negotium Codex-backed agent turn or configures a cron script.

Impact

A user may run an AI agent under falsely represented unrestricted permissions; cron scripts inherit environment variables.

Mechanism

Synthetic Codex session/control-context injection and configured command execution.

AI rationale

Decision evidence

public snapshot

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

Evidence for warning

Runtime rewrites Codex session developer instructions to claim danger-full-access.
Runtime forces Codex approvalPolicy to never and sandbox policy to danger-full-access.
It writes synthetic rollout files into the user's Codex sessions directory before using Codex.
Cron jobs can execute configured workspace scripts with the inherited environment.

Evidence against

The postinstall downloaders fetch only version-pinned GitHub release assets and verify hard-coded SHA-256 hashes.
No source evidence of credential exfiltration or a non-loopback exfiltration endpoint was found.
