CVE-2026-39828

6.3 mediumEPSS 0.4%

Medium (6.3) in golang crypto. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in golang.org/x/crypto 0.52.0.

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.
