Frequently Asked Questions
What does HIGH severity mean for CVEs?
CVSS 7.0–8.9 — serious vulnerabilities that can lead to significant data exposure, privilege escalation, or service disruption
How many high severity CVEs exist?
There are 143,102 CVE records rated HIGH in our database. Of these, 363 are listed in CISA's Known Exploited Vulnerabilities catalog.
How should I prioritize high severity vulnerabilities?
HIGH severity vulnerabilities should be patched immediately, especially if they are in the CISA KEV catalog or have a high EPSS score. Use CyberStrike to automatically detect and prioritize these vulnerabilities across your infrastructure.
