CVE-2026-39833 (GCVE-0-2026-39833)
Vulnerability from nvd – Published: 2026-05-22 02:31 – Updated: 2026-05-22 18:58

Title
Invoking key constraints not enforced in golang.org/x/crypto/ssh/agent
Summary
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.

CVE-2026-39832 (GCVE-0-2026-39832)
Vulnerability from nvd – Published: 2026-05-22 02:31 – Updated: 2026-05-22 19:03
VLAI
Title
Invoking agent constraints dropped when forwarding keys in golang.org/x/crypto/ssh/agent
Summary
When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.

CVE-2026-39832 (GCVE-0-2026-39832)
Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-05-22 19:03

Title
Invoking agent constraints dropped when forwarding keys in golang.org/x/crypto/ssh/agent
Summary
When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.

Title
Invoking key constraints not enforced in golang.org/x/crypto/ssh/agent
Summary
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.
