      "value": "Snipe-IT is an IT asset/license management system. Prior to 8.6.0, UsersController::update() passes a missing permission request field through NormalizePermissionsPayloadAction and PreserveUnauthorizedPrivilegedPermissionsAction in a way that can overwrite a target user’s permissions with a sparse result, allowing an administrator updating another administrator, or a user with users.edit updating a regular account, to remove the target’s administrative or granular permissions. This issue is fixed in version 8.6.0."

Previo a la versión 8.6.0, UsersController::update() pasa un campo de solicitud de permiso faltante a través de NormalizePermissionsPayloadAction y PreserveUnauthorizedPrivilegedPermissionsAction de forma que puede sobrescribir los permisos de un usuario objetivo con un resultado disperso, permitiendo que un administrador que actualiza a otro administrador, o un usuario con users.edit que actualiza una cuenta regular, elimine los permisos administrativos o granulares del objetivo. Este problema se corrige en la versión 8.6.0."
