sagentic@1.0.9

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 flagged auth file performs Turnstile verification, and the dynamic calculator evaluation is limited by an allowlist. The CLI’s credential transfer is part of user-invoked remote chat to the package’s Sagentic service; no independent malicious behavior was established.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user invokes the CLI and sends a chat message in remote mode.

Impact

The chat service receives the submitted message, workspace context, and authentication token for the intended remote service.

Mechanism

The CLI posts the message and workspace context to its Sagentic chat endpoint, using a configured API token or auth secret as a bearer token.

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json declares the server and CLI entry points, with no install lifecycle hook.
The calculator restricts expressions to arithmetic and named Math methods before evaluating them.
The auth module sends Turnstile verification data to Cloudflare’s verification endpoint.
The CLI sends its configured Sagentic API token or auth secret as a bearer token to the Sagentic chat endpoint when a user invokes remote chat.
The CLI sends the user’s message and workspace context as part of that chat request.

Evidence against

The CLI’s default recipient is the package’s Sagentic-branded chat service, and local mode is explicitly available.
The auth module’s external request is a Turnstile verification request; the flagged dynamic evaluation is constrained by an expression allowlist.
