## How to prioritise The Wikimedia Foundation patching

This order follows the data Threadlinqs holds for The Wikimedia Foundation, not a generic severity checklist:

- No The Wikimedia Foundation CVE is in CISA KEV yet, so rank by exploit probability instead.
- 2 CVEs have 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.
