Exploited now

Every vulnerability CISA confirms is being exploited in the wild: listed in its Known Exploited Vulnerabilities catalog, or assessed as actively exploited in its Vulnrichment data, often days before the catalog. When it was confirmed, how soon after the CVE went public, and the vendors attackers go after first. Refreshed every ten minutes. Sources.

What this means for a patch cycle

Half of the vulnerabilities CISA confirmed exploited in the last 12 months were confirmed within 4 days of going public, and 38% by the day they were published. A monthly patch cycle leaves those exposed for weeks. Products from the vendors below, especially internet-facing ones, need an emergency patch path measured in days.

Where attackers strike first

Vendors by vulnerabilities confirmed exploited in the last 24 months; the top five account for 67% of the twelve listed. This counts confirmed attacks, not disclosed flaws, so a vendor is not rewarded for publishing fewer CVEs. Mapped health IT products account for 1 of them.

How to read this

"Confirmed exploited" is the date CISA added the CVE to its Known Exploited Vulnerabilities catalog or assessed it as actively exploited, whichever came first. It is when exploitation was confirmed publicly, not when attackers started, so "after publication" is an upper bound: attackers were there at least that soon. "By disclosure day" means confirmed on or before the day the CVE record was published, the closest public measure of a zero-day. Dates are US Eastern, the calendar CISA uses. Vendors are named as CISA's catalog names them, otherwise as the assigning CNA does. EPSS is FIRST's estimate of the chance of exploitation in the next 30 days.
