Security audit

Tra Cuu Phat Nguoi

Security checks for vulnerabilities and agentic risk

Overview

This skill performs the traffic-fine lookup it claims to do, but users should know it sends plate data to a third-party intermediary site.

Install only if you are comfortable sending license plate details, and any phone number you provide, to vnetraffic.org, which the skill itself identifies as a non-official intermediary. Use official Vietnamese government or registration portals for final confirmation.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill instructs use of a networked script and external endpoint (vnetraffic.org) but does not declare any explicit tool scope or permissions in the skill metadata. This creates an authorization and review gap: a runtime may permit undeclared outbound network access, making data exfiltration, unexpected third-party calls, or privacy-impacting requests harder to audit and constrain.

Missing User Warnings

Confidence
95% confidence
Finding

The script transmits a vehicle plate number and optional phone number to a third-party endpoint (vnetraffic.org) without any explicit user disclosure, consent prompt, or minimization safeguards. License plates and phone numbers are sensitive personal data in context, and the default behavior of sending a fabricated fallback phone number further obscures what data is being submitted and may violate user expectations or privacy requirements.
