How to prioritise Splunk patching

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

  • 2 of 33 Splunk CVEs (6%) are in CISA KEV: treat them as actively exploited and remediate them first, starting with CVE-2026-20253, CVE-2026-20265.
  • Outside KEV, the highest EPSS scores are CVE-2026-20251 (32.2%), CVE-2026-20139 (5.2%), CVE-2026-20266 (0.6%).
  • 4 CVEs score Critical and 6 High on CVSS v3 (maximum 9.8, average 6.3); sequence these after KEV and high-EPSS items.
  • 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 2026-10-10 and refresh daily.
