GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2026-72830

Vulnerability from fkie_nvd - Published: 2026-08-14 12:16 - Updated: 2026-08-31 20:38
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
