CVE-2018-16874

• Severity: high (CVSS 8.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 5.0% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2018-12-14 · updated 2026-06-17
• Weakness: CWE-20

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.

• Go: before 1.10.6; from 1.11.0 before 1.11.3 — fixed in 1.10.6, 1.11.3
