CVE-2026-61498 VITEC CVE debrief

CVE-2026-61498 is an unauthenticated OS command injection vulnerability in Vitec Flamingo 4.12.2. The vulnerability exists in the admin/ajax/gen_graphs.php endpoint, allowing remote unauthenticated attackers to execute arbitrary commands by supplying shell metacharacters in the start, end, key, or format HTTP GET parameters. The vulnerability is caused by a lack of input sanitization in the graph generation script, which passes user-supplied values directly to shell commands via passthru(). This allows attackers to execute arbitrary OS commands with root privileges due to the web server context having passwordless sudo access.
