How to prioritise Mitsubishi Electric patching
This order follows the data Threadlinqs holds for Mitsubishi Electric, not a generic severity checklist:

- Outside KEV, the highest EPSS scores are CVE-2019-14931 (58.4%), CVE-2026-8806 (0.6%), CVE-2026-1874 (0.4%).
- 1 CVE scores Critical and 4 High on CVSS v3 (maximum 9.8, average 8.7); sequence these after KEV and high-EPSS items.
- 1 CVE has a public exploit or proof of concept recorded, which shortens the time from disclosure to attack.
