CVE-2026-94447Checksum database bypass for golang.org/toolchain in cmd/go

Go toolchain cmd/go Veröffentlicht: 2026-10-09 01:53 (vor 1 Monat)

Beschreibung

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.
