Alibaba Cloud AI Video Digital Human

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped helper for preparing Alibaba Cloud digital-human video requests and does not show hidden persistence or unrelated data access.

Before installing, confirm you are comfortable providing public image and audio URLs to Alibaba Cloud and managing DASHSCOPE_API_KEY or Alibaba Cloud credentials for provider use. Keep generated request and polling evidence under the documented output directory unless you intentionally choose another path.

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

MCP Least Privilege
Confidence
87% confidence
Finding
The skill declares no explicit tool scope or permissions boundary even though it instructs file-writing behavior via output artifacts and validation commands. In agent environments, missing scope declarations can allow broader-than-necessary filesystem access, making it easier for the skill to write outside intended directories or be composed with other capabilities unsafely.

Session Persistence

Medium
Category
Rogue Agent
Content
## Validation

```bash
mkdir -p output/aliyun-wan-digital-human
python -m py_compile skills/ai/video/aliyun-wan-digital-human/scripts/prepare_digital_human_request.py && echo "py_compile_ok" > output/aliyun-wan-digital-human/validate.txt
```
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.
