Embed a badge
A live badge for a README, a status page or an internal wiki: how many Microsoft Edge vulnerabilities were published in the last 7 days and how many of them are critical, refreshed hourly.
[](https://junglewise.ai/threats/technologies/edge)<a href="https://junglewise.ai/threats/technologies/edge"><img src="https://junglewise.ai/threats/technologies/edge/badge.svg" alt="Microsoft Edge vulnerabilities" /></a>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.
The pages are rebuilt from the database every hour. Frozen weekly and monthly reports never change once published, so they can be cited.
