## Products affected

Threadlinqs normalises CPE and CNA product records across all 9 CVEs; 2 distinct MZ Automation products are affected. The most frequently affected:

- libiec61850 — 8 CVEs
- lib60870 — 1 CVE

## Threat activity

No tracked threat campaign references MZ Automation products or CVEs yet. Vulnerability records are still monitored for exploitation and linked as campaigns are ingested.

## How to prioritise MZ Automation patching

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

- No MZ Automation CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-66360](https://intel.threadlinqs.com/cve/CVE-2026-66360) (0.3%), [CVE-2026-61893](https://intel.threadlinqs.com/cve/CVE-2026-61893) (0.3%), [CVE-2026-63550](https://intel.threadlinqs.com/cve/CVE-2026-63550) (0.2%).
- 0 CVEs score Critical and 1 High on CVSS v3 (maximum 7.5, average 6.6); 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.

## About this data

Vendor attribution comes from the CNA and CPE product records of each CVE, folded to one vendor name; CVSS, EPSS and KEV status are read from the Threadlinqs CVE catalog; campaign and actor links come from tracked threat records. Counts reflect the data as of 2026-10-05 and refresh daily.
