--- title: "CVE-2018-16874\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2018-16874?format=md keywords: index, follow --- # CVE-2018-16874 Publication date 14 December 2018 Last updated 26 August 2025 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **6.8 · Medium** [Score breakdown](https://ubuntu.com/security/CVE-2018-16874?format=md#impact-score) Toggle side navigation ## Description In Go before 1.10.6 and 1.11.x before 1.11.3, the "go get" command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (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.
