CVE-2023-29404

CWE-94Published: June 8, 2023· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. The arguments for a number of flags which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled through the LDFLAGS sanitization. This affects usage of both the gc and gccgo compilers.

Risk Analysis

The Go command is vulnerable to arbitrary code execution during build time due to improper sanitization of linker flags. This affects both the gc and gccgo compilers, allowing malicious modules to execute arbitrary code.

No public exploit is known, and the vulnerability is not in the KEV catalog. It is remotely exploitable with low attack complexity.

Recommended Action

Update the Go toolchain to the latest version and exercise caution when building untrusted code.
