Ory provides Cross-Site Request Forgery (CSRF) protection for all flows, including the registration form. This means that you must send a CSRF token in the body and CSRF cookie back when submitting a flow. The cookie should be sent by default by your browser, but you must add the CSRF token manually to the request body. This can be a JSON object or a native form POST. When mapping UI nodes, take note of input fields with the name

csrf_token

with the

hidden

attribute. This CSRF protection helps to prevent code injection attacks. However, while Ory provides CSRF protection, it's always a good practice to implement additional security measures on your end to protect your application from various types of attacks, including code injections. This could include validating and sanitizing user inputs, using parameterized queries, and so on. Here is an example of how you can map the UI nodes for CSRF protection:

javascript import {     Configuration,     FrontendApi,     LoginFlow,     UiNodeInputAttributes,   } from "@ory/client"   import {     filterNodesByGroups,     isUiNodeInputAttributes,   } from "@ory/integrations/ui"   import { useEffect, useState } from "react"      const frontend = new FrontendApi(     new Configuration({       basePath: "<http://localhost:4000>", // Use your local Ory Tunnel URL       baseOptions: {         withCredentials: true,       },     }),   )      function CsrfMapping() {     const [flow, setFlow] = useState<LoginFlow>()        useEffect(() => {       frontend.createBrowserLoginFlow().then(({ data: flow }) => setFlow(flow))     }, [])        return flow ? (       <form action={flow.ui.action} method={flow.ui.method}>         {filterNodesByGroups({           nodes: flow.ui.nodes,           // we will also map default fields here but not oidc and password fields           groups: ["default"],           attributes: ["hidden"], // only want hidden fields         }).map((node) => {           if (             isUiNodeInputAttributes(node.attributes) &&             (node.attributes as UiNodeInputAttributes).type === "hidden" &&             (node.attributes as UiNodeInputAttributes).name === "csrf_token"           ) {             return (               <input                 type={node.attributes.type}                 name={node.attributes.name}                 value={node.attributes.value}               />             )           }         })}       </form>     ) : (

Ory Kratos does not explicitly mention protection against JavaScript injection in form fields in the provided knowledge sources. However, it's generally a good practice to sanitize user inputs on the server side to prevent such attacks. This includes escaping special characters and removing any script tags from the input. When it comes to email content, it's important to ensure that any user-provided input included in the email is properly sanitized and escaped to prevent potential script execution. This is typically handled on the email client side (most modern email clients have built-in protections against executing scripts in email content), but it's still a good practice to sanitize the content on the server side as well. If you're using Ory Kratos's built-in email templates, it's likely that they have some level of protection against this type of attack, but it's not explicitly mentioned in the provided knowledge sources. If you're using custom email templates, you should ensure that you're properly sanitizing any user-provided input that's included in the email content.
