Vvvv Fileformat

Security checks for vulnerabilities and agentic risk

Overview

This skill is documentation for vvvv gamma .vl XML files and does not show hidden behavior, code execution, persistence, or data exfiltration.

Installers should understand that this skill guides agents in creating or modifying vvvv gamma .vl files. Review generated .vl changes as you would any code or project-file edit, especially dependencies in XML examples, but the skill itself does not request unusual access.

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
