The library does not distinguish between metadata a public registrant is allowed to set and administrative controls that should require operator approval.\n\nThis vulnerability is associated with program files lib/boruta/openid.ex and program routines 'Elixir.Boruta.Openid':register_client/3, 'Elixir.Boruta.Openid':parse_registration_params/2.\n\nThis issue affects boruta from 2.3.0 before 2.3.7."}, {"lang": "es", "value": "Vulnerabilidad de aislamiento o compartimentaci\u00f3n inadecuados en malach-it boruta (m\u00f3dulo Elixir.Boruta.Openid) permite a los atacantes registrar clientes OpenID Connect con privilegios administrativos a trav\u00e9s del punto de entrada de registro din\u00e1mico de clientes.
