Summary
MinIO is a Kubernetes native application for cloud storage. Prior to version `RELEASE.2021-12-27T07-23-18Z`, a malicious client can hand-craft an HTTP API call that allows for updating policy for a user and gaining higher privileges. The patch in version `RELEASE.2021-12-27T07-23-18Z` changes the accepted request body type and removes the ability to apply policy changes through this API. There is a workaround for this vulnerability: Changing passwords can be disabled by adding an explicit `Deny` rule to disable the API for users.

"value": "MinIO es una aplicaci\u00f3n nativa de Kubernetes para el almacenamiento en la nube. En versiones anteriores a \"RELEASE.2021-12-27T07-23-18Z\", un cliente malicioso puede elaborar manualmente una llamada a la API HTTP que permite actualizar la pol\u00edtica de un usuario y alcanzar mayores privilegios. El parche de la versi\u00f3n \"RELEASE.2021-12-27T07-23-18Z\" cambia el tipo de cuerpo de petici\u00f3n aceptado y elimina la posibilidad de aplicar cambios de pol\u00edtica mediante esta API. Se presenta una soluci\u00f3n para esta vulnerabilidad: El cambio de contrase\u00f1as puede deshabilitarse al a\u00f1adir una regla expl\u00edcita \"Deny\" para deshabilitar la API para los usuarios"
