## How to prioritise nodejs patching

This order follows the data Threadlinqs holds for nodejs, not a generic severity checklist:

- No nodejs CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-58040](https://intel.threadlinqs.com/cve/CVE-2026-58040) (0.2%), [CVE-2026-58039](https://intel.threadlinqs.com/cve/CVE-2026-58039) (0.2%), [CVE-2026-56847](https://intel.threadlinqs.com/cve/CVE-2026-56847) (0.2%).
- 1 CVE scores Critical and 2 High on CVSS v3 (maximum 10, average 6); sequence these after KEV and high-EPSS items.
