How to read this card

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — the theoretical maximum severity. Remotely exploitable, no privileges required, total impact. Not yet confirmed as exploited in the wild, but patch now. Widely used software only: a 10.0 in a niche plugin does not make it here.

AI-recommended

A language model reviewed the CVE and judged that it affects widely deployed software or common developer tooling. A human on the team approved publication before it landed here.

Impact categories the AI evaluates

widely_deployed_infra — Linux kernel, OpenSSL, glibc, k8s, Docker, nginx, OpenSSH.

popular_dev_tooling — Node.js, Python, Go, React, Next.js, common npm/pip libraries.

common_consumer_software — Chrome, Firefox, Windows, macOS, popular mobile apps.

enterprise_saas — GitHub, GitLab, Atlassian, Salesforce, Cisco, Fortinet, Ivanti.

niche_software — Regional CMSs, hobby tools, rarely used libraries.

not_relevant — Vendor-specific firmware, discontinued software.

EPSS — EPSS (Exploit Prediction Scoring System) by FIRST.org estimates the probability that a CVE will be exploited in the next 30 days. Range is 0 to 1; very fresh CVEs typically score low until evidence accumulates.
