How to read this brief

CVSS score (e.g. 9.1) โ€” severity from 0โ€“10. Red marks critical (9+), orange high (7โ€“8.9).

Exploitability โ€” how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical โ€” how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges โ€” the access they need first. No privileges means no login required.
  • No interaction / User interaction โ€” whether a victim has to do something (open a file, click a link). No interaction means fully automatable.

The lower the bar on all three, the easier to exploit at scale โ€” โ€œNetwork ยท No privileges ยท No interactionโ€ is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited โ€” confirmed under attack in the wild (CISAโ€™s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS ยท Nth percentile โ€” FIRST.orgโ€™s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% โ€” a statistical signal itโ€™s unusually likely to be targeted, separate from whether attacks are confirmed.
