Description
Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/toolchain go.sum entry and operates a malicious GOMODPROXY the user chooses to use can bypass the intended checksum.
We now ensure that golang.org/toolchain always goes to the network for the canonical checksum.
