CVE-2026-39832
CVE-2026-39832 · Invoking agent constraints dropped when forwarding keys in golang.org/x/crypto/ssh/agent
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Cette page présente une partie des faits des sources. Consultez les avis liés pour la description complète et les versions concernées.
When adding a key to a remote agent constraint extensions such as [email protected] 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.
