Alibaba Cloud AI Video Wan Edit

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow helper for preparing Alibaba Cloud Wan video-editing requests, with only disclosed local output-file writes and no hidden persistence or credential handling.

Before installing, note that this skill can create local output files for validation and request preparation. Review the generated request JSON before sending it to Alibaba Cloud or replacing the example video URL with real user content.

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

Finding
The skill performs file-writing behavior during validation and normal use (`output/.../validate.txt` and `request.json`) but does not declare any `permissions` or `allowed-tools` scope. This creates an authorization gap where an agent may invoke file-write capabilities without explicit policy constraints, making review and enforcement weaker.
