CVE-2020-8277 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of Service in versions < 15.2.1, < 14.15.1, and < 12.19.1 by getting the application to resolve a DNS record with a larger number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1.. EPSS estimates a 54.16% chance of exploitation in the next 30 days.
