How this is built
Junglewise Threat Intelligence collects vulnerabilities from NVD, GitHub Security Advisories, OSV, the CISA Known Exploited Vulnerabilities catalog, FIRST EPSS and vendor advisories, and matches each one to the technologies and vendors it affects. Dates are the date a vulnerability was published, in UTC.
Technologies are ranked by a score: 10 points for each vulnerability exploited in the wild, 5 for each critical, 2 for each high and 1 for every vulnerability. A vulnerability counts once for every technology it affects, so one advisory can appear under several products.
The pages are rebuilt from the database every hour. Frozen weekly and monthly reports never change once published, so they can be cited.
