Security checks for vulnerabilities and agentic risk

Overview

This Markdown-only skill is a coherent FlightGear/Nasal props reference that documents powerful simulator operations but does not install, persist, or execute anything itself.

Install this as documentation, not as an automation tool. When using its examples, be careful with live/global FlightGear property nodes, deletion methods, userarchive/preserve attributes, and props.runBinding; only run bindings or scripts from trusted, intentional property trees.

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 documents props.runBinding as a way to execute command bindings, including a nasal command example, without any warning that binding nodes can trigger privileged actions or script execution. In an agent setting, this can normalize turning untrusted property-tree data into executable actions, increasing the risk of command/script injection or unsafe UI/system operations if consumers apply it to attacker-controlled nodes.

Finding

This markdown file documents node removal operations such as .remove(), .removeChild(), .removeChildren(), and .removeAllChildren() but does not warn that they delete data from the active property tree and may be irreversible in context. For markdown files, SQP-2 applies when descriptions omit warnings about behaviors that could affect user data or system integrity.
