Security audit

MiniMax H3 爆款视频复刻 | LinkPix

Security checks for vulnerabilities and agentic risk

Overview

The skill is coherent for generating MiniMax H3 marketing videos through qhkit, with disclosed external API use and user confirmation before paid generation.

Install only if you are comfortable using the Qinghu/qhkit service, sharing the required API key with the local agent configuration, and uploading the referenced videos/images for processing. Review or pin npm tools in sensitive environments, and check the estimated credits 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

Findings (6)

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description contains very broad trigger language and a long list of generic marketing keywords, increasing the chance the skill will be invoked for loosely related requests. In agent environments, overbroad activation can route users into a workflow that installs tools, requests API keys, and performs external actions even when the user did not clearly ask for this specific capability.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The trigger section is underspecified and lacks exclusion conditions, telling the agent to activate on broad phrases like '对标' or '照着做' plus a social link. Given the skill also drives installation, configuration, and external service usage, ambiguous triggering raises the risk of unintended tool execution and unnecessary exposure of user data or credentials.

Finding

The skill instructs use of npx @iqinghu/qhkit without pinning a specific version, which allows whatever package version is current at execution time to be fetched and run. Because this is a network-retrieved executable used in an automation context, a malicious upstream release or dependency compromise could lead to arbitrary code execution on the host.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Finding

The skill recommends npx --yes sharp-cli with no version pin, causing a fresh package download and execution of the latest published package during image processing. In an agent or unattended workflow, this creates a supply-chain execution path where a compromised release could run arbitrary code under the user's privileges.
