sshkey-grab

sshkey-grab This script uses a bug in ssh-agent that allows it to pull the last key added to the agent. This may allow the ability to recover a key that has been removed from ssh-agent via ssh-add -t, -d, or -D, provided that the ssh-agent was not terminated and a new key has not been added since...

CVE-2026-116775

A flaw was found in pageant. A remote malicious server can trigger a Denial of Service DoS on a client system when SSH agent forwarding is bridged to a raw Pageant stream. By transmitting an excessively large frame length prefix, an attacker can force the client to buffer data without proper boun...

russh: russh: Denial of Service via resource exhaustion in SSH agent

A flaw was found in russh. When processing key addition requests containing lifetime constraints, the Secure Shell SSH agent server spawns a separate long-lived task for repeated constraint records and fails to roll back tasks if subsequent parsing fails. An attacker capable of communicating with...

russh: russh: Denial of Service via uncontrolled memory consumption in SSH agent

A flaw was found in russh. This vulnerability can lead to a Denial of Service DoS due to unbounded memory consumption in the SSH agent service. A local process or a remote user with access to a forwarded agent socket can repeatedly submit keys containing an excessive number of confirmation...

russh: russh: Unauthorized key signing via SSH agent confirmation bypass

A flaw was found in russh. When processing signing requests for SSH keys configured to require explicit confirmation, the SSH agent server component fails to invoke the confirmation check and automatically returns success. A local process or remote user with access to the forwarded SSH agent sock...
