Patch first

Exploited in the wild, newest first.

CISA adds a CVE to its Known Exploited Vulnerabilities catalog when attackers are using it. Patch these first, then CVEs with a high EPSS score, then the most severe, starting with anything reachable from the internet.

Reading the radar

CVSS, KEV and EPSS, briefly.

What is a CVE?

A CVE is a public identifier for one vulnerability in one product, such as CVE-2026-59310. The CVE program assigns it; NVD, run by the US National Institute of Standards and Technology, adds scores, weakness classes and affected product lists.

What does the CVSS score tell me?

CVSS rates how severe a vulnerability is on its own, from 0 to 10, and its vector says how it is reached: over the network or locally, with or without an account, with or without someone clicking. It says nothing about whether anyone is exploiting it. The radar shows the newest CVSS version scored and names it, because version 4.0 and 3.1 scores differ.

What is CISA KEV?

The Known Exploited Vulnerabilities catalog is CISA's list of CVEs with reliable evidence of exploitation in the wild. US federal agencies must fix each one by its due date, and it is the strongest signal of what to patch first.

What is EPSS?

FIRST's Exploit Prediction Scoring System estimates the probability that a CVE will see exploitation activity in the next 30 days, recomputed daily. Most CVEs score well under 1%, so the radar also shows the percentile: how a CVE ranks against every scored CVE.

How should I prioritise?

Patch what CISA lists as exploited first. Then CVEs with a high EPSS score, then the most severe by CVSS. Within each group, start with whatever is reachable from the internet without an account.

Where do the explanations come from?

Veriom writes them from fixed templates over each record: the weakness class says what went wrong and where in an architecture it lives, the CVSS vector says how it is reached and what it affects, and KEV, EPSS and CISA's assessment say whether it is exploited. Nobody reviews each CVE by hand, so read the description and the references before acting.

How fresh is the data?

New and changed CVEs arrive from NVD every hour, the KEV catalog every six hours and EPSS scores once a day. Each page shows when the data was last updated.

Know where a vulnerable component would sit in your systems.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
