IceCube Tasks

Security checks for vulnerabilities and agentic risk

Overview

This task-management skill stores task files for continuity, and that persistence is disclosed and aligned with its purpose.

Install only if you want task details saved in project files across sessions. Avoid putting secrets or sensitive personal information in task titles, descriptions, blockers, or history unless you are comfortable retaining that data on disk, and delete state/tasks entries when no longer needed.

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 explicitly instructs the agent to persist task data in files that survive restarts and context compaction, but it provides no warning that user-provided content may be retained across sessions. This creates a privacy and data-retention risk because sensitive prompts, project details, blockers, assignments, or metadata may be written to disk unexpectedly and remain accessible later.
