Security checks for vulnerabilities and agentic risk

Overview

The skill makes clearly disclosed public marketplace requests, with user approval and no authority to spend money.

Keep the default review setting and check every public request for confidential details, including budget information. Protect RSSA_TOKEN, and review any quote or future service purchase separately. Stopping use does not automatically remove existing posts.

  • 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
