Affected Components(2)
Go logotoolchain
1.27.0-0 – 1.27.2

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.
