Technical description

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.

———The Grav API plugin (getgrav/grav-plugin-api) before 1.0.13 contains an API-key scope-cap bypass in UsersController's create() and update() methods. These methods enforce the scope cap only for api.users.write, but gate super-privilege grants on a bare isSuperAdmin() check that reads access.api.super directly without consulting the key's scopes. As a result, an api.users.write-scoped key minted on a super account can set access.api.super or assign a super-granting group to mint or promote a full super account, then authenticate as that account for uncapped administrative privileges.6h CVE-2026-728287.2 HIG

———Grav Plugin API (getgrav/grav-plugin-api) before 1.0.13 fails to enforce API-key scope caps in InvitationsController. The strip-super and accept-groups decisions are gated on a bare isSuperAdmin() check rather than a scope-aware permission check, so a least-privilege API key (scoped to api.users.write) minted on a super account can create an invitation record containing super-admin access flags. When the invitation is accepted, those flags are written verbatim to the new account, resulting in privilege escalation to a fully controlled super account.9h CVE-2026-180398.1 HIG
