Security audit

NZTA Traffic

Security checks for vulnerabilities and agentic risk

Overview

This skill only queries New Zealand traffic information from the public NZTA Traffic and Travel API and does not show hidden, persistent, credential-seeking, or destructive behavior.

Install this if you want a command-based helper for New Zealand state highway traffic, closures, roadworks, and camera lookups. Be aware it contacts trafficnz.info and should be used for NZTA/New Zealand highway questions rather than generic traffic requests.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill invokes a shell script but does not declare any tool scope or allowed-tools restrictions, so an agent may be permitted to execute shell commands more broadly than intended. In an agent environment, this weakens containment and can enable unintended command execution paths if the skill is triggered or modified later.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest description includes example invocations such as "how's the traffic" and "any road closures," which are broad natural-language phrases that could be used in ordinary conversation outside an explicit request to invoke this skill. The description does not provide tighter activation constraints or negative examples to clarify when the skill should and should not trigger.
