CVE-2026-72829 is an API-key scope-cap bypass vulnerability in the Grav API plugin before version 1.0.13. The flaw resides in the UsersController create() and update() methods, which enforce scope restrictions for api.users.write but use a separate isSuperAdmin() check to gate super-privilege assignment. That check reads access.api.super directly and does not evaluate the effective scopes of the API key being used. As a result, an api.users.write-scoped key minted under a super-admin account can create a new user or modify an existing user to set access.api.super or assign a group that confers super privileges. This allows escalation from a scoped API key to a fully privileged super-admin account.
