Seedance 2.0 爆款视频复刻 | LinkPix

Security checks for vulnerabilities and agentic risk

Overview

The skill’s video-generation purpose is coherent, but it asks the agent to install and update unpinned command-line tools and store service credentials, which deserves review before use.

Install this only in an environment where you are comfortable letting the agent install or update npm/Node tooling, store a qhkit API token, and upload reference videos or product images to the qhkit/iqinghu service. Prefer a disposable workspace, preinstall a reviewed qhkit version yourself if possible, avoid sensitive media, and verify the quoted credit cost before approving any generate command.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The manifest description says the skill "must" trigger on a long keyword list including broad terms like "抖音", "TikTok", "小红书", "种草视频", and "短视频起号". These terms are common topic words rather than narrowly scoped invocation phrases, so they could cause unintended activation during ordinary discussion of social-media marketing.

Vague Triggers

Category

Confidence
86% confidence
Finding

The "何时触发" section gives examples such as using Seedance 2.0 to recreate a viral video, but it does not define negative cases or clearly separate this skill from adjacent tasks like generic video generation, analysis, or platform discussion. That ambiguity increases the risk of this skill being invoked outside its intended clone/recreation workflow.

Finding

The skill instructs use of npx @iqinghu/qhkit without pinning an exact version, which permits execution of whatever package version is current at install time. That creates a supply-chain risk: a compromised latest release or dependency could be fetched and executed in the agent environment, especially because the command is framed as a fallback path for missing tooling.

Session Persistence

Medium
Category
Rogue Agent
Confidence
84% confidence
Finding

This duplicate finding points to the same persistence behavior: unpacking Node.js into a user-controlled directory and exporting a modified PATH. In a skill that may execute automatically, persistent tooling bootstrap increases the blast radius of mistakes or future package compromise because later sessions may inherit the installed runtime.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The instructions state that the CLI message is already user-facing Chinese and should be relayed directly to the user. This implies a fixed language behavior rather than offering the user a language choice, which can violate language/locale policy when users have not opted into Chinese output.

Finding

The fallback image-compression command uses npx --yes sharp-cli with no pinned version, causing an on-demand download and execution of the latest package. In an automated agent workflow, this widens the attack surface to npm supply-chain compromise and makes builds non-reproducible.
