What CISA added to its Known Exploited Vulnerabilities catalog this month
These 48 vulnerabilities were added to CISA’s KEV catalog in the last 45 days — flaws CISA has confirmed attackers are actively exploiting, each with its own remediation due date under BOD 26-04. Not a severity score or a prediction on its own: an entry only appears here once CISA has evidence of exploitation in the wild and a fix exists. Each row also carries FIRST.org’s EPSS score, an independent, separately-computed estimate of the probability that a flaw will be exploited in the next 30 days — CISA’s KEV list tells you a flaw has already been used in an attack; EPSS tells you how likely continued exploitation is right now. New to these terms? See the security glossary.
Updated
Built by Daily CISO from CISA’s own KEV JSON feed (catalog version 2026.11.06, 1769 entries total going back to 2021; counts, due dates and the newest additions across the whole catalog are on the KEV tracker) and FIRST.org’s EPSS API (scores dated November 7, 2026); not an official CISA or FIRST.org page. This page lists the newest 45 days of KEV additions and drops off older ones — the full catalog stays on CISA’s own site, linked from every row below. Snapshot taken November 8, 2026.
For the vulnerabilities Microsoft fixes each month, not just the ones CISA has confirmed under attack, see Patch Tuesday.
