      "value": "Grav is a file-based Web platform. In Grav 2.0.0-beta.2, a low-privileged authenticated API user with api.media.write can abuse /api/v1/blueprint-upload to write an arbitrary YAML file into user/accounts/, then log in as the newly created account with api.super privileges. This results in full administrative compromise of the Grav API. This vulnerability is fixed in API 1.0.0-beta.17."

En Grav 2.0.0-beta.2, un usuario de API autenticado con privilegios bajos y con api.media.write puede abusar de /api/v1/blueprint-upload para escribir un archivo YAML arbitrario en user/accounts/, y luego iniciar sesión como la cuenta recién creada con privilegios api.super. Esto resulta en un compromiso administrativo total de la API de Grav. Esta vulnerabilidad se corrige en la API 1.0.0-beta.17."
