Flux Board

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clear Flux API reference for managing kanban data, with disclosed write capabilities and no hidden code or persistence.

Install only with a Flux API key whose scopes match the actions you want the agent to perform. Review write operations such as creating, moving, assigning, commenting on, or deleting cards and boards before approving them, especially in shared workspaces.

A.I.G

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
