CVE-2026-39828
highpriority · track · 0EPSS 0.004 · 31 %ileDEEUFRRUUSEPSS · scored 2026-10-27
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.
