Exploited vulnerabilities, ranked by what to fix first.

Every item below is confirmed as exploited in the wild by CISA. We rank each one by how likely it is to be used against you in the next 30 days and how severe it is, so you know what to patch today and what can wait for the next cycle.

              How we rank

              Exploited first, then likelihood and impact.

              Severity scores alone send teams chasing thousands of “critical” findings that are never attacked. Starting from what is actually being exploited, then adding the probability of exploitation, focuses effort where attackers are.

              Act now

              Used in ransomware, an exploit probability of 50% or more in the next 30 days, critical severity (CVSS 9+), or rated by CISA as automatable with total impact. Patch or mitigate internet-facing systems within days.

              This week

              Exploit probability of 10% or more, high severity (CVSS 7+), or rated by CISA as automatable at scale. Schedule into this week’s change window.

              Plan

              Exploited, but less likely to be used against you soon. Fix within your normal patch cycle, before the CISA date.
