Recommended action

Update golang.org/x/crypto to 0.52.0; golang.org/x/crypto/ssh to 0.52.0 if you use the affected versions. Test the change in a non-production environment first.

What this means

golang.org/x/crypto/ssh: Invoking byte arithmetic causes underflow and panic affects golang.org/x/crypto (go), golang.org/x/crypto/ssh (go). Severity is high. An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs.

AI coding agents often install or upgrade packages automatically in go. A high 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.
