Security Advisory ADV200002 (https://portal.msrc.microsoft.com/en-us/security-guidance/advisory/ADV200002):
QuoteThis advisory will be updated whenever Microsoft releases a version of Microsoft Edge (Chromium-based) which incorporates publicly disclosed security updates from the Chromium project. Microsoft will document separately any vulnerabilities in Microsoft Edge (Chromium-based), that are not in Chromium, under a Microsoft-assigned CVE number (see, for example: CVE-2020-1341 (https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/cve-2020-1341)).
To check for Microsoft Edge security updates, click the three dots located in the upper right-hand corner, select Settings > About Microsoft Edge or merely put edge://settings/help in the address bar. When going to that page, Edge will automatically check for any updates.
