Video Editor - 视频剪辑

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent local video-editing skill, with ordinary file-output risks but no evidence of hidden network access, persistence, credential access, or malicious behavior.

Install only if you want a local Chinese-language video-editing helper. Check output filenames before running commands, especially merge, audio extraction, talk-video generation, or any command where you provide an explicit output path, because existing files may be overwritten.

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

Findings (4)

Lp3

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.

Vague Triggers

Medium

Confidence: 93% confidence
Finding: The trigger list includes broad phrases such as '加文字', '变速', and '视频处理', which can match many ordinary user requests and cause the skill to activate unexpectedly. Unintended invocation is risky because this skill performs local media transformations that could overwrite files, consume resources, or act on the wrong content if selected automatically.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The skill describes commands that trim, merge, resize, replace audio, and otherwise transform media, but it does not warn about overwriting existing files, destructive edits, or the need to use separate output paths and backups. In a local file-processing skill, missing safety guidance increases the chance of accidental data loss or user confusion, especially when users may assume in-place edits are safe or reversible.

Natural-Language Policy Violations

Medium

Confidence: 96% confidence
Finding: This code file contains user-facing natural-language descriptions and CLI output exclusively in Chinese, including the module docstring and command descriptions. Because it forces a specific language for interaction without any user opt-in or documented locale constraint, it violates the language/locale policy criterion.
