cmd/go: Checksum Database Bypass for golang.org/toolchain Downloads

This advisory does not affect KrakenD

The vulnerable code path only runs inside the go command line tool (cmd/go) while downloading toolchains. KrakenD’s compiled binary never invokes the Go toolchain or fetches modules at runtime.

Addressed through routine dependency maintenance in CE 3.0.1 and EE 3.0.1, 2.13.11.

Component

Go toolchain (cmd/go)

Description

A malicious project carrying a bogus go.sum entry for golang.org/toolchain, combined with a malicious GOPROXY, could make the go command skip the checksum database check when downloading a toolchain, so an untrusted toolchain could be used. The fix always fetches the canonical toolchain checksum from the network. This is a build-time issue in the Go toolchain and does not affect KrakenD.
