AI description

Automated description summarized from trusted sources.

CVE-2025-61731 describes a vulnerability within the `cmd/go` component of the Go programming language. This flaw involves a bypass of the `CgoPkgConfig` flag. The bypass associated with the `CgoPkgConfig` flag can result in arbitrary code execution. This issue was identified and reported by RyotaK of GMO Flatt Security.

Description: Building a malicious file with cmd/go can cause can cause a write to an attacker-controlled file with partial control of the file content. The "#cgo pkg-config:" directive in a Go source file provides command-line arguments to provide to the Go pkg-config command. An attacker can provide a "--log-file" argument to this directive, causing pkg-config to write to an attacker-controlled location.
