CVE-2026-39828

Опубликовано: 22 мая 2026
Источник: ubuntu
Приоритет: medium
EPSS Низкий
CVSS3: 6.3

Описание

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.
