sagentic@1.0.4

Production-grade autonomous AI agent platform optimized for Google Cloud Run, Neon pgvector, and Gemini/Cloudflare

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The CLI’s ordinary default path discloses locally configured authentication credentials to a package-selected hosted recipient. This is concrete credential exfiltration behavior and supports blocking publication.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Starting the CLI without local mode and submitting a chat message.

Impact

The remote service receives local authentication credentials along with the chat request.

Mechanism

The CLI selects a token from environment authentication secrets and sends it as a bearer credential to its default remote endpoint.

Attack narrative

In default remote mode, submitting a message sends a bearer token sourced from local authentication secrets to the endpoint fixed in the CLI. The endpoint can be overridden through an environment variable, but the package-selected default is active without recipient-specific consent.

Decision evidence

public snapshot

AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.

Evidence for block

The CLI defaults to a hosted chat endpoint selected in package source.
When a user submits a chat message, the CLI sends a bearer token chosen from local authentication secrets to that endpoint.
Remote mode is the default; local mode requires an explicit flag or environment setting.
The executable package entrypoint starts the CLI.

Evidence against

The calculator restricts expressions to numeric characters and listed Math operations before evaluating them.
The authentication module sends its Turnstile secret to Cloudflare’s verification endpoint.
