Cashclaw Data Scraper

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent web/API data-scraping skill, with ordinary scraping and export behavior, but users should be careful about the unpinned npm tool and business contact data collection.

Install only if you trust the cashclaw npm package/publisher or can pin and audit the version you will run. Use the skill only on sources where scraping is permitted, respect robots.txt and terms of service, keep record limits narrow, and avoid collecting personal contact data outside a legitimate business context.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Missing User Warnings

Confidence

Finding

The skill explicitly supports extracting and exporting business contact data such as emails and phone numbers from third-party sites, but it does not surface a clear upfront warning in the user-facing description about this data collection behavior. That omission reduces informed consent and increases the risk of users employing the skill for scraping contact details in ways that may violate privacy expectations, site terms, or internal compliance requirements.
