CVE-2026-39828 | BDVDB-2026-334548 Detail
golang.org/x/cryptogolang.org/x/crypto/ssh
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact low. Attack vector: network.
