How to prioritise Kiteworks patching

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

• No Kiteworks CVE is in CISA KEV yet, so rank by exploit probability instead.
• Outside KEV, the highest EPSS scores are CVE-2026-23514 (1%), CVE-2026-102142 (0.4%), CVE-2026-102144 (0.4%).
• 2 CVEs score Critical and 5 High on CVSS v3 (maximum 9.4, average 7.4); 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 2026-10-25 and refresh daily.
