Security audit

OpenVid

Security checks for vulnerabilities and agentic risk

Overview

This skill is a documented paid video-generation API integration that clearly discloses sending prompts and public URLs to OpenVid.

Before installing, confirm you are comfortable paying for each generated video through the documented wallet/payment flow and only submit public URLs or non-sensitive prompt text. Note that README pricing includes longer, higher-priced durations than the shorter pricing table in SKILL.md, so users should verify the price shown by the 402 payment response before authorizing payment.

A.I.G

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
