Runwayml

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Runway API helper; it discloses that it needs internet access, an API key, and sends prompts or media to Runway to generate content.

Install this only if you are comfortable sending the prompts, images, videos, or audio you provide to Runway's API and storing a Runway API key in your environment. Review Runway's own API terms and billing because generation calls consume account credits.

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
