CVE-2026-61498Public exploitNetwork attack vector

Unauthenticated root command execution via graph parameters

Published Jul 13, 2026 · Updated Jul 13, 2026

Unauthenticated OS command injection in VITEC Flamingo 4.12.2 allows remote attackers to execute arbitrary commands via graph parameters. The admin/ajax/gen_graphs.php script passes the start, end, key, and format GET values directly into shell commands through passthru() without sanitization. No credentials or user interaction are required, and passwordless sudo in the web-server context grants the injected commands root privileges.
