CVE-2026-73281: OpenBSD OpenSSH

Low severity, CVSS 3.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.

Affected products
