Doc Text:
A flaw was found in OpenSSH. When built using certain macOS software development kits (SDKs), the SSH server daemon (sshd) disables process sandboxing due to the removal of underlying system interfaces. Consequently, the daemon runs without sandbox isolation, potentially allowing an attacker who compromises the service to access system resources that would normally be restricted.

Description OSIDB Bzimport 2026-10-06 21:31:18 UTC
In sshd in OpenSSH through 10.6, use of the macOS 27 (or later) SDK has the side effect of loss of sandboxing, which is potentially unexpected.
