Description

A command injection vulnerability in FTP-Flask-python through 5173b68 allows unauthenticated remote attackers to execute arbitrary OS commands. The /ftp.html endpoint's "Upload File" action constructs a shell command from the ftp_file parameter and executes it using os.system() without sanitization or escaping.
