Description
I marked some fields as private fields in user content-type, and tried to register as a new user via api, at the same time I added content to fill the private fields and sent a post request, and as you can see from the images below, I can write to the private fields.
To prevent this, I went to the extension area and tried to extend the register method, for this I wanted to do it using the sanitizeInput function that I know in the source codes of the strap. But the sanitizeInput function did not filter out private fields.
const { auth } = ctx.state;
const data = ctx.request.body;
const userSchema = strapi.getModel("plugin::users-permissions.user");
sanitize.contentAPI.input(data, userSchema, { auth });here's the solution I've temporarily kept to myself, code snippet
const body = ctx.request.body;
const { attributes } = strapi.getModel("plugin::users-permissions.user");
const sanitizedData = _.omitBy(body, (data, key) => {
const attribute = attributes[key];
if (_.isNil(attribute)) {
return false;
}
//? If you want, you can throw an error for fields that we did not expect.
// if (_.isNil(attribute))
// throw new ApplicationError(`Unexpected value ${key}`);
// if private value is true, we do not want to send it to the database.
return attribute.private;
});
return sanitizedData;
