Security checks for vulnerabilities and agentic risk

Overview

This is a coherent travel checklist skill with limited, disclosed data use and no executable code, persistence, or hidden authority.

Installers should expect Chinese-language instructions and output templates. Before connecting travel accounts, confirm you want the skill to read only minimal itinerary fields such as dates, locations, carrier or hotel details, and baggage rules; it explicitly says not to request or store passport numbers, payment details, API keys, or tokens.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Confidence
90% confidence
Finding

The default prompt is hardcoded in English ('Use $travel-checklist-hy...'), which imposes a language choice without indicating any user preference or opt-in. The surrounding metadata is in Chinese, making the forced language selection more clearly a locale/language policy concern.
