GO-2022-0190
Directory traversal via "go get" command in cmd/go
Quick fix
GO-2022-0190 — toolchain: upgrade to the fixed version with the command below.
go get toolchain@v1.10.6Details
The "go get" command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly brace (both '{' and '}' characters).
Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). The attacker can cause an arbitrary filesystem write, which can lead to code execution.
