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
