CVE-2025-57633

Critical severity, CVSS 9.8. EPSS: 1.4% chance of exploitation in the next 30 days.

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.
