GO-2026-5005 / CVE-2026-39833 —
ssh/agentNewKeyring()silently accepted keys with theConfirmBeforeUseconstraint but never enforced it — keys would sign without any confirmation prompt. Now returns an error when unsupported constraints are requested.Credited to: NCC Group Cryptography Services, sponsored by Teleport
GO-2026-5019 / CVE-2026-39831 —
sshVerify()for FIDO/U2F key types (sk-ecdsa-sha2-nistp256@openssh.com,sk-ssh-ed25519@openssh.com) did not check the User Presence flag, so signatures generated without physical touch were accepted. Unattended hardware key use was possible.Credited to: NCC Group Cryptography Services, sponsored by Teleport
GO-2026-5020 / CVE-2026-39834 —
sshWriting data larger than 4GB in a single
Writecall on an SSH channel caused an integer overflow in the payload size calculation, spinning indefinitely sending empty packets. Fixed by usingint64for the size comparison.Credited to: NCC Group Cryptography Services, sponsored by Teleport
