What would you fix first?

The advisories below are ordered by the Vulnetix risk prioritization strategy: exploitation evidence first, scores second. On the interactive page you can switch to three other lenses.

• Vulnetix priority default
  Malware first, then the KEV catalogues, then weaponized and observed exploitation, and only then the scores.
• Vendor rating
  The vendor's own words, ranked in the vendor's own order.
• CVSS score
  The CVSS base score the vendor published, or the highest score in the Vulnetix VDB when the vendor published none.
• EPSS likelihood
  FIRST’s exploit prediction. Advisories that resolve to no CVE have no EPSS and sort last.
