Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
cmd/go in Go before 1.16.14 and 1.17.x before 1.17.7 can misinterpret branch names that falsely appear to be version tags. This can lead to incorrect access control if an actor is supposed to be able to create branches but not tags.
