CVE-2026-61498
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVitec Flamingo 4.12.2 contains an unauthenticated OS command injection vulnerability in the admin/ajax/gen_graphs.php endpoint that allows remote unauthenticated attackers to execute arbitrary commands by supplying shell metacharacters in the start, end, key, or format HTTP GET parameters. Attackers can exploit the lack of input sanitization in the graph generation script, which passes user-supplied values directly to shell commands via passthru(), to execute arbitrary OS commands with root privileges due to the web server context having passwordless sudo access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceUnauthenticated OS command injection in Vitec Flamingo 4.12.2 admin/ajax/gen_graphs.php endpoint. Attackers can inject arbitrary shell commands via unsanitized HTTP GET parameters (start, end, key, format) passed directly to passthru(), achieving root-level code execution due to passwordless sudo configuration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Vitec Flamingo versionLocate the installation directory and check version files (e.g., version.php, VERSION.txt, or admin/config.php) for the installed Flamingo version numberAffected if installed version matches 4.12.2 exactly or is lower than 4.12.2
-
Verify vulnerable endpoint existsCheck for the presence of admin/ajax/gen_graphs.php in the web document root or application installation pathAffected if the file admin/ajax/gen_graphs.php exists on the system
-
Check sudo configuration for web server userRun 'sudo -l' as the web server user (www-data, apache, nginx) without a password to enumerate passwordless sudo rulesAffected if the web server user has passwordless sudo privileges configured in /etc/sudoers or /etc/sudoers.d/
-
Test parameter acceptance on gen_graphs.phpSend a benign HTTP GET request to admin/ajax/gen_graphs.php with test values for start, end, key, and format parameters and observe if they are processedAffected if the endpoint accepts and processes these GET parameters without validation errors
User is affected if Vitec Flamingo version is 4.12.2 or lower, the gen_graphs.php endpoint exists, and the web server user has passwordless sudo privileges enabling root-level command execution through the injection point.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation/whitelisting on the gen_graphs.php endpoint to block shell metacharacters, and remove passwordless sudo privileges from the web server user context.
