Vulnerability Report: GO-2023-2383

• CVE-2023-45285
• Affects: cmd/go
• Published: Dec 06, 2023

Using go get to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. GOPROXY=off).
