Discord Context

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Discord forum context cache that uses a bot token and local workspace memory files for its stated purpose.

Install this only for a Discord bot token with minimal server and channel access, and use an intended OpenClaw workspace because the skill reads and writes files under that workspace's memory tree. Review cached context before sharing it elsewhere.

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 invokes a Node.js CLI that uses both environment access and network connectivity to talk to Discord, but the manifest does not declare an explicit tool scope such as permissions or allowed-tools. That creates an authorization gap: an orchestrator or reviewer cannot easily constrain or reason about what the skill is allowed to access, increasing the chance of over-privileged execution and misuse of the Discord token or outbound network access.
