GO-2025-3383 — toolchain: upgrade to the fixed version with the command below.

go get toolchain@v1.24.0-rc.2

Details

Credentials provided via the new GOAUTH feature were not being properly segmented by domain, allowing a malicious server to request credentials they should not have access to. By default, unless otherwise set, this only affected credentials stored in the users .netrc file.
