Kanbanflow Skill

Security checks for vulnerabilities and agentic risk

Overview

This small KanbanFlow skill is coherent and limited to task-board commands, with only a minor caution that deletion is not explained as destructive.

Before installing, be aware that this skill includes task mutation commands, including delete. Use it only with a KanbanFlow board where the agent is allowed to change or remove tasks, and confirm deletion intent in your own workflow if task recovery matters.

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

Finding

The skill exposes a destructive command, kanbanflow delete <taskId>, but the description and usage provide no warning that deletion is irreversible or potentially destructive. This can lead to accidental data loss, especially if an agent or user invokes the command without explicit confirmation semantics or understanding of its impact.
