How we rank vulnerabilities
A vulnerability joins this list as soon as CISA adds it to its KEV catalog or ENISA flags it as exploited in the EUVD.
The CheckOps priority index, out of 10, combines severity (CVSS), the probability of exploitation within 30 days (EPSS, FIRST) and public exploitation signals.
Above 8, we recommend patching within 24 hours; above 6, or as soon as a vulnerability is exploited, within 7 days.
