K Cinema Bridge

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped Korean cinema lookup helper that fetches public, unauthenticated movie data and does not install code, request credentials, or persist changes.

Installers should understand that the skill relies on an external public GitHub Pages API refreshed daily, so movie availability and rankings should be treated as informational rather than authoritative ticketing data.

A.I.G

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
