Security checks across malware telemetry and agentic risk

Overview

This instruction-only AI answer skill is not shown to be malicious, but it uses an automatic paid x402 payment flow without clearly documented spending limits or per-request approval.

Before installing or using this skill, confirm that you trust cpbox.io/cppay.finance and the x402 payment helper. Configure a strict spending limit or isolated wallet, require confirmation before paid calls, and do not include sensitive information in prompts unless you are comfortable sending it to the external provider.

ASI03: Identity and Privilege Abuse
Medium
What this means

If configured with payment credentials, an agent using this skill could incur pay-per-use charges without a clearly documented confirmation or budget limit.

Why it was flagged

The skill expects a client to sign payment authorizations and says the payment process is automatic, but the artifact does not show user approval, spending caps, or wallet/payment scoping.

Skill content
Client signs (EIP-712) -> PAYMENT-SIGNATURE ... With `@springmint/x402-payment` or `x402-sdk-go`, payment is **automatic**.
Recommendation

Use only with a constrained payment wallet or account, require explicit approval before each paid request, and verify the x402 payment requirements and price before signing.

#
ASI04: Agentic Supply Chain Vulnerabilities
Low
What this means

Running the helper can execute code fetched from the npm ecosystem, so trust depends on the external package and its current published version.

Why it was flagged

The documented workflow runs an external npm package through npx, and the artifact does not pin a version or include that package for review.

Skill content
npx @springmint/x402-payment \
  --url https://www.cpbox.io/api/x402/answers
Recommendation

Pin and verify the payment helper package version, review its provenance, and prefer a locally installed trusted version for payment handling.

ASI02: Tool Misuse and Exploitation
Info
What this means

Questions and any included context are sent to the cpbox.io service for processing.

Why it was flagged

The skill sends user prompts to a disclosed third-party API endpoint, which is expected for an AI answer proxy but should be visible to users.

Skill content
curl -X POST "https://www.cpbox.io/api/x402/answers" ... "messages": [{"role": "user", "content": "How does the James Webb Space Telescope work?"}]
Recommendation

Avoid sending sensitive or confidential information unless you trust the provider and its data-handling terms.
