Summary
Go net/http from 0 before 1.26.9, net/http/internal/http2 from 1.27.0-0 before 1.27.2, and golang.org/x/net/http2 before 0.60.0 are affected. Asymmetric resource consumption (CWE-405) lets a malicious HTTP/2 peer drive excessive CPU use in a client or server. The peer opens many streams and then sends many small SETTINGS frames carrying SETTINGS_INITIAL_WINDOW_SIZE values.

Description from the CNA
A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGS_INITIAL_WINDOW_SIZE values.
