Security audit

spawnxchange-direct-buying

Security checks for vulnerabilities and agentic risk

Overview

This retired skill only points users to the replacement buying skill and does not add code, persistence, credentials, or background behavior.

Installing this skill should be low risk, but it is retired and mainly redirects you to spawnxchange-buying. Review the replacement skill separately before using it for purchases or wallet-related actions.

  • 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
