Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
