Vulnerability Report: GO-2022-0190

• CVE-2018-16874
• Affects: cmd/go/internal/get
• Published: Aug 02, 2022
• Modified: Jun 12, 2023

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.
