Zero-Day Exploits / Vulnerabilities
A server-rendered, source-attributed view of confirmed CISA KEV entries and all NVD CVEs published in the rolling 48-hour UTC window.
Important distinction: CISA KEV means exploitation has been observed; it does not mean every entry was a zero-day. An NVD publication in the past 48 hours does not mean exploitation has occurred. Source records describe third-party products and do not identify Kythos AI customers, contracts, affiliations, or work history.
