Vvvv Fundamentals

Security checks for vulnerabilities and agentic risk

Overview

This skill is a documentation-only guide to vvvv gamma fundamentals and does not ask the agent to run hidden commands or persist itself.

This appears safe to install as a reference skill for vvvv gamma development. Be aware that some examples describe vvvv APIs that can persist editor or channel state inside vvvv projects, so review generated project changes as you normally would.

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
Vulnerability Patterns
  • Rogue AgentSelf-Modification, Session Persistence
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Session Persistence

Medium
Category
Rogue Agent
Content
- `IChannel<T>` — observable value container
- `IChannel<T>.Value` — read/write the current value
- `Channel.IsValid()` — check if connected
- Channels persist state across sessions
- Enable two-way data binding between UI and patch

For C# channel integration patterns (IChannelHub, PublicChannelHelper, [CanBePublished]), see vvvv-channels.
Confidence
75% 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.
