Una vulnerabilidad en versiones anteriores a la 2.17.6 afecta a los usuarios que: autorizaron una aplicaci\u00f3n que solicit\u00f3 un alcance de \"escritura de token\" o, utilizando frontend-2, crearon un token de acceso personal (PAT) con alcance de \"escritura de token\". Al crear un nuevo token, un agente debe autorizar la solicitud con un token existente (el \"token solicitante\"). Se requiere que el token solicitante tenga alcance de escritura de token para poder generar nuevos tokens. Sin embargo, el servidor Speckle no estaba verificando que otros privilegios otorgados al nuevo token no excedieran los privilegios del token solicitante. Un actor malintencionado podr\u00eda utilizar un token con alcance de escritura de token \u00fanicamente para generar posteriormente m\u00e1s tokens con privilegios adicionales. Estos privilegios solo otorgar\u00edan permisos hasta los privilegios existentes del usuario. Esta vulnerabilidad no se puede utilizar para escalar los privilegios de un usuario ni otorgar permisos en nombre de otros usuarios. Esto ha sido parcheado a partir de la versi\u00f3n 2.17.6. Todos los operadores de servidores Speckle deben actualizar su servidor a la versi\u00f3n 2.17.6 o superior. Cualquier usuario que haya autorizado una aplicaci\u00f3n con alcance de \"escritura de token\" o haya creado un token en frontend-2 con alcance de \"escritura de token\" debe revisar los tokens existentes y revocar permanentemente los que no reconozcan, revocar los tokens existentes y crear nuevos tokens, y revisar uso de su cuenta para actividades sospechosas.
