CVE-2026-72830: Improper privilege management vulnerability

Grav API plugin versions before 1.0.13 fail to enforce API key scope caps in ConfigController super-scope gates, allowing scoped keys to write scheduler configuration. The scope cap is applied only inside requirePermission(), while the scheduler and backups gates use a bare isSuperAdmin() check that never consults api_key_scopes. An attacker holding an API key scoped to api.config.write that was minted on a super account can therefore inject arbitrary commands into scheduler.custom_jobs, which Job::run() passes to a Symfony Process, achieving operating system command execution as the web server user.
