Vvvv Patching

Security checks for vulnerabilities and agentic risk

Overview

This is a small documentation-only skill for vvvv gamma patching guidance, with no executable behavior or hidden authority.

This skill appears safe to install for vvvv gamma development help. Users should treat it as domain-specific guidance; for generic C#, non-vvvv visual programming, or unrelated event-handling questions, confirm that the skill's advice actually applies.

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

Vague Triggers

Medium
Confidence
93% confidence
Finding
The description says to use the skill when the user asks about "patching best practices, dataflow patterns, event handling, or how to structure visual programs," which is a broad natural-language activation condition rather than a narrowly defined trigger. It does not provide exclusion conditions or negative examples, so the skill could be invoked for generic programming-architecture questions beyond the intended vvvv gamma scope.

Session Persistence

Medium
Category
Rogue Agent
Content
Channels provide two-way data binding:
- `IChannel<T>` — observable value container
- `.Value` — read or write the current value
- Channels persist state across sessions
- Connect channels between nodes for reactive updates without explicit links

## Event Handling
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.
