CVE-2026-72833: Improper Privilege Management in getgrav grav
The Grav API plugin (getgrav/grav-plugin-api) versions >= 1.0.6 and <= 1.0.11 contain a privilege escalation vulnerability. A scoped API key minted on a super-admin account bypasses its declared scope cap on four isSuperAdmin()-gated write endpoints (in GroupsController, AccountsConfigController, PreferencesController, and DashboardWidgetController). These endpoints authorize via a super-admin early-return that never invokes requirePermission()—the sole enforcement point of the scope cap—so a 'read-only'-scoped key (e.g. api.pages.read) can perform super-only write operations, including rewriting group ACL maps to grant super-admin privileges to arbitrary accounts. A leaked or delegated read-only CI/monitoring key can therefore gain full super-admin write capability. Fixed in 1.0.13.
AI Analysis
Technical Summary
The Grav API plugin versions >=1.0.6 and <=1.0.11 contain a privilege escalation vulnerability where a scoped API key created on a super-admin account bypasses its declared scope cap on four isSuperAdmin()-gated write endpoints. These endpoints authorize via a super-admin early-return that does not invoke requirePermission(), which is the only enforcement point of the scope cap. Consequently, a read-only scoped key (e.g., api.pages.read) can perform super-admin write operations, including modifying group ACL maps to grant super-admin privileges to arbitrary accounts. This allows an attacker with access to a leaked or delegated read-only CI/monitoring key to gain full super-admin write capability. The vulnerability is fixed in version 1.0.13.
Potential Impact
An attacker with access to a scoped API key minted on a super-admin account, even if the key is read-only scoped, can escalate privileges to perform super-admin write operations. This includes modifying access control lists to grant super-admin privileges to arbitrary accounts, potentially leading to full system compromise. The vulnerability poses a high risk due to the ability to bypass intended permission restrictions.
Mitigation Recommendations
A fix is available in Grav API plugin version 1.0.13. Users should upgrade to version 1.0.13 or later to remediate this vulnerability. Until patched, restrict access to API keys minted on super-admin accounts and monitor for unauthorized privilege escalations.
