Security audit

Maoyan

Security checks for vulnerabilities and agentic risk

Overview

This is a simple movie-ticketing and box-office guidance skill with no executable behavior or hidden access.

Before installing, expect this skill to provide general guidance about Maoyan ticketing and box-office interpretation, mostly in Chinese. Confirm live ticket prices, refunds, showtimes, and box-office figures directly in Maoyan or Maoyan Pro because the skill itself contains static guidance only.

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

Natural-Language Policy Violations

Low
Confidence
82% confidence
Finding
The description on L04 combines Chinese and English and the overall skill is written primarily in Chinese, but there is no statement that the skill supports multiple languages or that the user can choose their preferred language. Under the policy for natural-language issues, forcing or assuming a language without opt-in can be a locale/language policy concern.
