CVE-2024-56145Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via forged CLI options

Published Dec 18, 2024 · Updated Oct 21, 2025

Code injection in Craft CMS before 3.9.14, 4.13.2, and 5.5.2 allows remote attackers to execute arbitrary code via HTTP requests. The web bootstrap passes PHP-populated argv values to App::cliOption, letting query-string options replace trusted configuration and template paths. No authentication or user interaction is required, but PHP register_argc_argv must be enabled and an attacker-controlled template must be reachable.
