## How to prioritise openchoreo patching

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

- No openchoreo CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-73667](https://intel.threadlinqs.com/cve/CVE-2026-73667) (0.6%), [CVE-2026-73666](https://intel.threadlinqs.com/cve/CVE-2026-73666) (0.5%), [CVE-2026-73841](https://intel.threadlinqs.com/cve/CVE-2026-73841) (0.4%).
- 2 CVEs score Critical and 3 High on CVSS v3 (maximum 9.6, average 8.3); sequence these after KEV and high-EPSS items.

## 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.
