When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
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.

hol-guard supply-chain scangolang.org/x/crypto/ssh vulnerable to invoking bypass of certificate restrictions affects golang.org/x/crypto (go), golang.org/x/crypto/ssh (go). Severity is medium. When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
AI coding agents often install or upgrade packages automatically in go. A medium 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.
