CVE search

This runs in your browser against four free public sources; there is no server cache in between. Answers you have already fetched stay in this tab for 12 hours (6 for the KEV catalogue) and a failed re-read falls back to the last good copy, labeled Stale with its fetch date, for up to 14 days. NVD's keyless allowance is five requests per 30 seconds, so the tool paces itself and a big batch takes a few minutes. CISA's catalogue sends no cross-origin header, so many browsers refuse the download; when that happens the KEV row reads Unavailable and the tool claims no KEV verdict at all, rather than inferring one from NVD's embedded exploited tags. Scores from different authorities can disagree; each row keeps its own label. This is a lookup, not a scanner: nothing here tests your systems, and the KEV remediation text is quoted as CISA wrote it.
