AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection did not confirm the scanner’s credential-exfiltration claim: the flagged embedding path downloads a public model, while worker routing uses the configured provider URL. The manifest has no consumer install hook, and the inspected agent setup prompts before changing configuration, so mark the package clean.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

The embedding download occurs when the embedding backend needs the model; agent configuration changes occur through the interactive setup command.

Impact

No unauthorized credential transfer or agent control change was established.

Mechanism

The model file is downloaded from Hugging Face. The setup command asks before writing the agent configuration and preserves it when the user declines.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json declares only a prepublishOnly script; it has no preinstall, install, or postinstall hook.
The CLI asks before updating the user’s agent configuration, and declines leave it unchanged.
The flagged embedding path downloads a public model file from Hugging Face for local use; the worker routes requests to the configured provider URL.
The inspected source did not establish credential theft, hidden agent configuration changes, or another concrete attack.

Evidence against

Static hints label credential exfiltration, but the inspected embedding path contains no credential handling and its download is model setup.
The package’s prepublishOnly command runs a build and a worker command; it is not a consumer install hook.
