The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKeyring() now returns an error when unsupported constraints are requested.
Update golang.org/x/crypto to 0.52.0; golang.org/x/crypto/ssh/agent to 0.52.0 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in go. A critical vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
