CISA KEV Deadline Planner

CISA KEV Deadline Planner is a tiny local-first web tool for turning pasted CVEs, scanner output, or vulnerability-management notes into a prioritized Known Exploited Vulnerabilities planning queue. It extracts CVE IDs, matches them against a bundled CISA KEV catalog snapshot, sorts overdue and due-soon entries, flags CISA ransomware-campaign-use markers, and exports Markdown, CSV, or ICS planning holds.

I built it for quick vulnerability review workflows where a user needs to answer: which pasted CVEs are in KEV, which due dates are already overdue, and which entries should be reviewed this week. The tool is intentionally static and private: no signup, no cookies, no analytics, no beacons, no uploads, no browser storage, and no external scripts. It is unofficial and tells users to verify current CISA, vendor, applicability, and exposure details before acting.
