CVE-2026-59995

A flaw was found in OpenSSH. The sftp client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or placing malicious files in sensitive directories on the client system, which could compromise system integrity.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, avoid using the sftp server:/path . command when connecting to untrusted or potentially malicious SFTP servers. Exercise caution and verify the authenticity of SFTP servers before initiating file transfers, especially when using commands that implicitly define the download destination, and also avoid running SFTP sessions with elevated privileges (such as root).
