Remote exploitation required that a user establishes an SSH connection to a compromised or malicious SSH server with agent forwarding enabled. The agent forwarding is disabled by default. Review your ssh client configuration files for the use of ForwardAgent configuration directive and invocations of ssh client for the use of -A command line argument to see if agent forwarding is enabled for specific connections. Exploitation can also be prevented by starting ssh-agent(1) with an empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring an allowlist that contains only specific provider libraries.
