## Products affected

Threadlinqs normalises CPE and CNA product records across all 10 CVEs; 1 distinct CoreWCF product is affected. The most frequently affected:

- CoreWCF — 10 CVEs

## Threat activity

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

## 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](https://intel.threadlinqs.com/cve/CVE-2026-54775) (0.3%), [CVE-2026-54779](https://intel.threadlinqs.com/cve/CVE-2026-54779) (0.3%), [CVE-2026-54782](https://intel.threadlinqs.com/cve/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.
