How to prioritise CoreWCF patching
This order follows the data Threadlinqs holds for CoreWCF, not a generic severity checklist:
- No CoreWCF CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are CVE-2026-54775 (0.3%), CVE-2026-54779 (0.3%), CVE-2026-54782 (0.2%).
- 1 CVE scores Critical and 4 High on CVSS v3 (maximum 10, average 6.6); 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.
