CVE-2026-65711Public exploitNetwork attack vector

Authenticated command execution via unescaped backup path

Published Jul 24, 2026 · Updated Jul 24, 2026

OS command injection in nuxsmin sysPass 3.2.11 and earlier allows remote authenticated users to execute commands via a malicious backup path. FileBackupService concatenates siteBackupPath into a tar command without shell escaping before passing the resulting string to exec(). Administrator access is required to save the path and trigger a backup; injected commands then run as the web server process user.
