Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only FlightGear Nasal props reference; it describes powerful in-engine APIs but does not install code, persist itself, or hide behavior.

Installers should understand that this skill teaches APIs capable of changing FlightGear simulator state. Treat examples involving global properties, attribute changes, removals, aliases, and runBinding as live-effect examples when adapted into real code.

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

Low

Confidence: 83% confidence
Finding: The skill documents props.runBinding as a way to execute command bindings, including a nasal command example, without clearly warning that this can trigger arbitrary in-engine actions and script execution with side effects. In an agent skill context, this is more dangerous because downstream systems may operationalize examples or expose them to automation, turning documentation into an execution primitive.
