openssh: OpenSSH: ssh-agent allows remote execution of local operations
Published Aug 11, 2026
3.5
LOWCVSS 3.1
EPSS 0.16%
Description
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.

Remediation
Red Hat statement
Red Hat has determined that this vulnerability has limited impact. Exploitation requires an authenticated SSH session with agent forwarding enabled and the agent in a locked state. Only OpenSSH versions 8.9 and later contain the vulnerable session-bind@openssh.com extension code. Red Hat Enterprise Linux 6, 7, 8, and RHEL 9 through 9.6 ship OpenSSH versions prior to 8.9 and are not affected. Red Hat may apply this fix in a future update for affected products.
Red Hat mitigation
Avoid using ssh-agent forwarding to untrusted remote hosts, or disable agent forwarding entirely by removing `ForwardAgent yes` from SSH configuration. If agent forwarding is required, avoid locking the agent while forwarded sessions are active.
