Security audit

Seedance 2.0 电商带货视频 | LinkPix

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed ecommerce video-generation workflow, but users should review its package-install and API-token setup before using it.

Before installing, confirm you are comfortable letting the agent install npm tooling, configure a qhkit API token, upload selected product media to the service, and spend account credits only after you approve the generated-task parameters.

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

  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest says the skill 'must trigger' when users ask to use Seedance 2.0 for '带货/商品/种草/广告视频', and also lists many broad keywords such as TikTok, Amazon, 商品动态展示, and 电商带货视频. These terms are common across many unrelated commerce-video workflows, so the activation scope is not narrow enough to prevent unintended invocation.

Finding

The skill instructs use of npx @iqinghu/qhkit without pinning a specific version, which allows execution of whatever package version is current at invocation time. In a security-sensitive agent environment, this creates a supply-chain risk: a compromised, malicious, or breaking upstream release could be fetched and executed automatically.

Session Persistence

Medium
Category
Rogue Agent
Confidence
89% confidence
Finding

This duplicate finding describes the same session-persistence behavior: unpacking a runtime into the user's home directory and altering PATH. In an agent setting, this is risky because it changes future execution context and could be abused or cause unintended side effects across subsequent tasks.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The instructions require sending a specific Chinese guidance message to users and repeatedly state that error messages should be relayed in Chinese, with no opt-in or language-selection path. This is a natural-language policy concern because it hard-codes a user-facing language instead of offering a locale choice.

Confidence
95% confidence
Finding

The instruction npx --yes sharp-cli downloads and executes the latest CLI package without version pinning. Because it is presented as an automatic fallback for image processing, an agent following this skill could run unreviewed third-party code from the registry, creating a direct supply-chain execution path.

Finding

The '何时触发' section gives only positive examples for activation and does not define non-matching cases. Without exclusion conditions, similar requests for broader video generation or adjacent workflows could incorrectly trigger this skill.
