What is CVE-2024-45340?

A security flaw in the GOAUTH feature of the Go programming language allows malicious servers to access user credentials improperly. This occurs because credentials are not correctly isolated by domain, potentially permitting unauthorized requests for sensitive information. By default, this issue primarily impacts credentials stored in the user's .netrc file, increasing the risk of unauthorized access. Developers using Go should review their configurations and ensure proper domain segmentation to safeguard user credentials.

Affected Version(s)

cmd/go 1.24.0-0 < 1.24.0-rc.2
