Security checks for vulnerabilities and agentic risk

Overview

This skill is a small wrapper guide for a summarization CLI, with external model and extraction services disclosed but privacy implications worth noting.

Install only if you are comfortable using an external summarization CLI and sending selected content to your configured model provider or optional extraction services. Avoid using it on confidential local files, private URLs, or sensitive media unless you have approval and understand which provider keys and fallback services are enabled.

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 encourages users to summarize URLs, local files, and YouTube links via external model providers and optional extraction/fallback services, but it does not clearly warn that submitted content may be transmitted off-host to third parties. This creates a real data exposure risk because users may pass sensitive local documents, private URLs, or copyrighted/media content under the assumption the operation is local or self-contained.
