CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated command injection vulnerability in the remote backup transfer feature that allows authenticated attackers to execute arbitrary OS commands by controlling a remote server's API response. Attackers can inject malicious commands through a crafted directory name in the remote server's API response, which bypasses security middleware validation and is passed unsanitized to the OS command execution function.
