Doc Text:
A flaw was found in OpenSSH's `ssh-agent` component. A misinteraction between agent locking and the `session-bind@openssh.com` extension allows operations intended for local execution to be performed remotely. This could enable a remote attacker to add PKCS#11 tokens or utilize keys with destination restrictions, bypassing intended security controls.

Description OSIDB Bzimport 2026-08-11 19:31:58 UTC
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 extension.
