OpenSSH 10.6 removes the shared LZ77 compression dictionary across multiplexed SSH channels after researchers showed it could leak plaintext when attackers can inject and observe traffic in the same session. The release also rejects usernames containing $ and \ in command-line contexts to prevent shell interpretation through directives like ProxyCommand and Match exec.
