Aerobase Calendar

Security checks for vulnerabilities and agentic risk

Overview

This skill describes a coherent Google Calendar sync feature for travel events, with sensitive calendar read/write behavior that is expected for its purpose but should be clearly confirmed by users before use.

Install only if you want Aerobase to connect to Google Calendar for travel syncing. Before enabling it, confirm what calendar scopes are granted, whether automatic event creation or removal can be previewed or disabled, and how to disconnect the integration if you no longer want syncing.

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

Missing User Warnings

Finding
The skill describes reading a user's upcoming calendar events and creating or modifying calendar entries, but it provides no user-facing warning, consent language, or scope minimization guidance. Because calendar data is highly sensitive and write access can alter a user's personal or work schedule, this omission increases the risk of unexpected data access and unauthorized-seeming modifications, especially when the agent automatically syncs flights and recovery events.
