Ntriq X402 Screenshot Data Batch

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward paid API call for screenshot extraction, with the main caution that screenshots and extracted data are sent to a third-party service.

Before installing or using this skill, only submit screenshots you are authorized to share with the provider. Review or redact credentials, customer data, internal dashboards, personal information, and regulated data, and prefer short-lived private URLs where possible. Also confirm the x402 payment details before sending a request.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The skill instructs users to send up to 500 screenshot URLs to a third-party remote endpoint and receive extracted contents, but it provides no privacy warning about the sensitivity of screenshots or the fact that image contents and derived data are transmitted off-box. Screenshots commonly contain credentials, personal data, internal dashboards, API keys, or customer information, so omission of a warning can lead users to disclose sensitive information unintentionally.
