Capcut

Security checks for vulnerabilities and agentic risk

Overview

This skill only guides agents to summarize public CapCut website information and does not request private access, code execution, persistence, or account actions.

Installers should be aware that the skill is written in Chinese and is meant for public CapCut information gathering only. Do not use it for private CapCut projects, account actions, paid-resource access, or copyright-bypass workflows.

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

Natural-Language Policy Violations

Finding
The file’s natural-language instructions and descriptions are entirely in Chinese, and there is no indication that users may choose another language or that the skill is intentionally restricted to a Chinese-speaking context. Under the policy, forcing a specific language without user opt-in can be a locale/language policy violation.
