internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.

A flaw was found in OpenSSH. The internal-sftp component within sshd incorrectly processes command-line arguments, recognizing only the first nine. This limitation can prevent the application of intended security configurations for SFTP (SSH File Transfer Protocol) connections, potentially leading to a bypass of security properties.
