codex-ultra workbench launcher: server compiled locally with Bun + web UI (cxu starts it all).

AI Security Review

scanned 12d ago · by lpm-firewall-ai

No attack surface was established. Install-time work stays inside the package-owned .cxu server directory, and agent binary discovery plus optional vendor installers are user-invoked CLI behavior.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm postinstall runs the local server compile; cxu commands run only when the user launches the CLI.

Impact

The consumer gets a local workbench server and optional official tool installers. No unconsented foreign agent-config write, credential export, or hidden payload execution was found.

Mechanism

postinstall copies bundled server assets and may compile them with bun. The CLI looks up local agent binaries and runs an installer only after an install command or a prompt.

AI rationale

The postinstall hook compiles this package's own server into ~/.cxu and does not rewrite another agent's control files. Agent install commands in the obfuscated CLI are gated by an explicit user command or prompt, and the pty code is ordinary node-pty.

Decision evidence

public snapshot

AI called this Clean at 74.0% confidence as Benign with medium false-positive risk.

Why the final policy warns

The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. A high or critical static finding has no usable source path. These conditions do not mean that the AI confirmed malicious behavior.
