This document requires ‘trustedHTML’ assignment: what does it mean and how to fix it?

Avatar

Have you ever been asked to “trust” a document before opening it? If so, you’ve likely encountered a document that has been assigned a “trusted HTML” label. This label indicates that the document has been scanned for malicious content and has been deemed safe to open.

But what exactly is “trusted HTML”? And how can you be sure that a document with this label is actually safe?

In this article, we’ll take a closer look at trusted HTML and explain how it can help you protect yourself from malicious documents. We’ll also provide some tips for identifying and avoiding documents that have been falsely labeled as trusted.

What is trusted HTML?

Trusted HTML is a security feature that is used to protect users from malicious documents. When a document is assigned a trusted HTML label, it means that it has been scanned for malicious content and has been deemed safe to open.

The trusted HTML feature is based on a set of rules that are used to scan documents for malicious content. These rules are designed to identify documents that contain viruses, worms, Trojan horses, and other types of malicious code.

If a document does not pass the trusted HTML scan, it will not be assigned a trusted HTML label and will not be able to be opened. This helps to protect users from accidentally opening malicious documents and exposing their computers to infection.

How can you be sure that a document with a trusted HTML label is safe?

While the trusted HTML feature is a valuable security tool, it is important to remember that it is not foolproof. There is always the possibility that a malicious document could be falsely labeled as trusted.

That’s why it is important to exercise caution when opening any document, even if it has a trusted HTML label. Here are a few tips for identifying and avoiding documents that have been falsely labeled as trusted:

  • Only open documents from trusted sources. This is the most important tip for avoiding malicious documents. If you don’t know the source of a document, don’t open it.
  • Scan documents with a virus scanner before opening them. Even if a document has been assigned a trusted HTML label, it is still a good idea to scan it with a virus scanner before opening it. This will help to protect you from any malicious content that may have been missed by the trusted HTML scan.
  • Be suspicious of documents that ask you to enable macros or JavaScript. Malicious documents often contain macros or JavaScript that can be used to install malware on your computer. If a document asks you to enable macros or JavaScript, be very careful and only do so if you are sure that the document is from a trusted source.

By following these tips, you can help to protect yourself from malicious documents and keep your computer safe.

What is TrustedHTML?

TrustedHTML is a security feature that is used to prevent malicious code from being executed in a web browser. It works by verifying that the HTML code that is being loaded has been signed by a trusted publisher. This prevents attackers from injecting malicious code into a website and tricking users into running it.

TrustedHTML is implemented by the browser, and it works by checking the digital signature of the HTML code that is being loaded. The signature is a unique identifier that is generated when the HTML code is created. The browser checks the signature against a list of trusted publishers, and if the signature is valid, the HTML code is loaded. If the signature is not valid, the browser will block the HTML code from being loaded.

TrustedHTML is a very effective security feature, but it can also be a burden for developers. This is because developers need to create signed HTML code in order for it to be loaded in a browser. This can be a time-consuming process, and it can also be difficult to get right.

Despite the challenges, TrustedHTML is an important security feature. It helps to protect users from malicious code, and it is a valuable tool for developers who want to create secure websites.

Why is TrustedHTML required?

TrustedHTML is required for a number of reasons. First, it helps to protect users from malicious code. Malicious code can be used to steal personal information, install malware, or even take control of a user’s computer. TrustedHTML helps to prevent this by blocking malicious code from being executed in a web browser.

Second, TrustedHTML helps to protect websites from being compromised. If a website is compromised, an attacker could inject malicious code into the website and trick users into running it. TrustedHTML helps to prevent this by blocking malicious code from being loaded in a browser.

Third, TrustedHTML helps to protect businesses from data breaches. Data breaches can be very costly for businesses, and they can damage their reputation. TrustedHTML helps to prevent data breaches by blocking malicious code from being executed on a computer.

Overall, TrustedHTML is a very important security feature. It helps to protect users, websites, and businesses from malicious code. It is a valuable tool for developers who want to create secure websites.

How to implement TrustedHTML?

TrustedHTML is a security feature that allows you to specify which HTML tags and attributes are allowed on your website. This can help to prevent cross-site scripting (XSS) attacks, which are a type of attack that can be used to steal user credentials or inject malicious code into a website.

To implement TrustedHTML, you need to add the following code to your website’s header:

This code will tell the browser to only allow HTML tags and attributes that are listed in the `trusted-types.min.js` file. You can find a list of the allowed tags and attributes in the [Trusted Types documentation](https://trustedtypes.org/docs/).

Once you have added the code to your website’s header, you need to make sure that all of your HTML tags and attributes are listed in the `trusted-types.min.js` file. If you have any tags or attributes that are not listed, the browser will not allow them to be rendered on your website.

You can add tags and attributes to the `trusted-types.min.js` file by following these steps:

1. Open the `trusted-types.min.js` file in a text editor. 2. Find the section of the file that lists the allowed tags and attributes. 3. Add your tags and attributes to the list. 4. Save the file.

Once you have added your tags and attributes to the `trusted-types.min.js` file, you need to recompile the file. You can do this by running the following command in the terminal:

npm run build

Once the file has been recompiled, you can deploy it to your website.

Common TrustedHTML errors

There are a few common errors that you can make when implementing TrustedHTML. These errors can prevent your website from working properly or they can make it vulnerable to XSS attacks.

1. Not including the `Content-Security-Policy` header

The `Content-Security-Policy` header is required for TrustedHTML to work. If you do not include this header, your website will not be protected from XSS attacks.

2. Not using the `trusted-types.min.js` file

The `trusted-types.min.js` file is required for TrustedHTML to work. If you do not use this file, your website will not be protected from XSS attacks.

3. Not including all of your tags and attributes in the `trusted-types.min.js` file

You need to make sure that all of your tags and attributes are listed in the `trusted-types.min.js` file. If you do not include all of your tags and attributes, the browser will not allow them to be rendered on your website.

4. Using invalid tags or attributes

You can only use tags and attributes that are listed in the `trusted-types.min.js` file. If you try to use a tag or attribute that is not listed, the browser will not allow it to be rendered on your website.

5. Using tags or attributes incorrectly

You need to make sure that you are using tags and attributes correctly. If you use them incorrectly, the browser may not be able to render them properly or it may be vulnerable to XSS attacks.

6. Not updating the `trusted-types.min.js` file

The `trusted-types.min.js` file is updated regularly with new tags and attributes. You need to make sure that you are using the latest version of the file. If you are not using the latest version, your website may not be protected from new XSS attacks.

TrustedHTML is a powerful security feature that can help to protect your website from XSS attacks. However, it is important to implement TrustedHTML correctly in order to avoid common errors. By following the steps in this document, you can help to ensure that your website is protected from XSS attacks.

Prevent DOM-based cross-site scripting vulnerabilities with Trusted Types

Reduce the DOM XSS attack surface of your application.

Krzysztof Kotowicz

Why should you care?

DOM-based cross-site scripting (DOM XSS) is one of the most common web security vulnerabilities, and it's very easy to introduce it in your application. Trusted Types give you the tools to write, security review, and maintain applications free of DOM XSS vulnerabilities by making the dangerous web API functions secure by default. Trusted Types are supported in Chrome 83, and a polyfill is available for other browsers. See Browser compatibility for up-to-date cross-browser support information.

For many years DOM XSS has been one of the most prevalent—and dangerous—web security vulnerabilities.

There are two distinct groups of cross-site scripting. Some XSS vulnerabilities are caused by the server-side code that insecurely creates the HTML code forming the website. Others have a root cause on the client, where the JavaScript code calls dangerous functions with user-controlled content.

To prevent server-side XSS , don't generate HTML by concatenating strings and use safe contextual-autoescaping templating libraries instead. Use a nonce-based Content Security Policy for additional mitigation against the bugs as they inevitably happen.

Now a browser can also help prevent the client-side (also known as DOM-based) XSSes with Trusted Types .

API introduction

Trusted Types work by locking down the following risky sink functions. You might already recognize some of them, as browsers vendors and web frameworks already steer you away from using these features for security reasons.

  • Script manipulation : <script src> and setting text content of <script> elements.

Generating HTML from a string :

innerHTML , outerHTML , insertAdjacentHTML , <iframe> srcdoc , document.write , document.writeln , and DOMParser.parseFromString

Executing plugin content : <embed src> , <object data> and <object codebase>

Runtime JavaScript code compilation : eval , setTimeout , setInterval , new Function()

Trusted Types require you to process the data before passing it to the above sink functions. Just using a string will fail, as the browser doesn't know if the data is trustworthy:

To signify that the data was securely processed, create a special object - a Trusted Type.

Trusted Types heavily reduce the DOM XSS attack surface of your application. It simplifies security reviews, and allows you to enforce the type-based security checks done when compiling, linting, or bundling your code at runtime, in the browser.

How to use Trusted Types

Prepare for content security policy violation reports.

You can deploy a report collector (such as the open-source go-csp-collector ), or use one of the commercial equivalents. You can also debug the violations in the browser: js document.addEventListener('securitypolicyviolation', console.error.bind(console));

Add a report-only CSP header

Add the following HTTP Response header to documents that you want to migrate to Trusted Types. text Content-Security-Policy-Report-Only: require-trusted-types-for 'script'; report-uri //my-csp-endpoint.example

Now all the violations are reported to //my-csp-endpoint.example , but the website continues to work. The next section explains how //my-csp-endpoint.example works.

Identify Trusted Types violations

From now on, every time Trusted Types detect a violation, a report will be sent to a configured report-uri . For example, when your application passes a string to innerHTML , the browser sends the following report:

This says that in https://my.url.example/script.js on line 39 innerHTML was called with the string beginning with <img src=x . This information should help you narrow down which parts of code may be introducing DOM XSS and need to change.

Fix the violations

There are a couple of options for fixing a Trusted Type violation. You can remove the offending code , use a library , create a Trusted Type policy or, as a last resort, create a default policy .

Rewrite the offending code

Perhaps the non-conforming functionality is not needed anymore or can be rewritten in a modern way without using the error-prone functions?

trustedhtml assignment

Use a library

Some libraries already generate Trusted Types that you can pass to the sink functions. For example, you can use DOMPurify to sanitize an HTML snippet, removing XSS payloads.

Create a Trusted Type policy

Sometimes it's not possible to remove the functionality, and there is no library to sanitize the value and create a Trusted Type for you. In those cases, create a Trusted Type object yourself.

For that, first create a policy . Policies are factories for Trusted Types that enforce certain security rules on their input:

This code creates a policy called myEscapePolicy that can produce TrustedHTML objects via its createHTML() function. The defined rules will HTML-escape < characters to prevent the creation of new HTML elements.

Use the policy like so:

Use a default policy

Sometimes you can't change the offending code. For example, this is the case if you're loading a third-party library from a CDN. In that case, use a default policy :

Switch to enforcing Content Security Policy

When your application no longer produces violations, you can start enforcing Trusted Types:

Voila! Now, no matter how complex your web application is, the only thing that can introduce a DOM XSS vulnerability, is the code in one of your policies - and you can lock that down even more by limiting policy creation .

Hi nefoeddannwyl,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

I understand that you are experiencing issues with YouTube videos being slow to start up and taking a long time to open. TIt seems like the messages you're encountering about "Trusted URL assignment" and "Trusted HTML assignment" may be related to security settings in your web browser. These messages might indicate that some features on certain websites, like YouTube, require specific permissions to run properly.

To address the slow video playback, I recommend checking your internet connection speed and ensuring that it meets the minimum requirements for streaming videos. You can also try clearing your browser cache and cookies to see if the issue persists.

Disclaimer: Your browser automatically saves temporary internet files to help pages load faster. Clearing this cache will sometimes fix website issues. Please back up all your personal files first, such as Favorites, to ensure you do not lose data.

If the issue persists, try accessing YouTube using a different web browser to see if the problem is specific to your current browser.

Disable browser extensions or add-ons one by one to identify if any of them are causing the slow performance. Some extensions might interfere with YouTube's functionality.

Regarding the blue dotted circle that continues to go around, this may indicate that your computer is experiencing performance issues.

I hope this helps.  If there is anything not clear, please do not hesitate to let me know.

Your Sincerely

Hahn - MSFT | Microsoft Community Support Specialist

? If the whole script breaks before it even started, it may be due to @require scripts that were blocked by a restrictive Trusted-Types CSP (Content Security Policy). This script might help. It also tries to be useful in cases where the script can run, but regular old string assignments are now blocked.

This is mainly to enable TamperMonkey to continue using scripts that have @require dependencies on sites with a restrictive Trusted-Types policy.

Although TT is still an experimental feature, Google seems quite keen to enforce it already, albeit half-assedly, where supported. Ugh! >.<

This script provides pass-through policies to try to enable you to do what ever you want with the DOM, while trying not to disturb any defaults in place. Basically, if you have to create your own Trusted Types (e.g. TrustedHTML), and if the site's CSP allows for the creation of new policies, you can use a permissive policy to wrap your strings into a Trusted Type, like TrustedHTML, which the browser will then allow you to assign to the DOM. Best case scenario: The site has no default policy set. This allows us to specify our own, in which we can then allow everything (pass-through); this will restore all ability to modify the DOM. If we have to create a custom policy, all contents have to be piped through the relevant function of the TT Policy, like TTP.createHTML("unsafe string contents") , which will then return trusted contents.

Fixing scripts that break trying to @require dependencies due to Trusted-Types CSP

Just activate this script, it'll try its best to mend the situation. If it doesn't work: Try setting overwrite_default to true . This is disabled by default because it might break functionality on the site, if it relies on its own default policy to do something specific. If it still doesn't work: The site's CSP may have disallowed the creation of our own policies, in which case there's nothing we can do just yet. Send me feedback with the usual details (url, browser and TM version, output of your Browser Console, etc) to see if there's anything I can do.

Modifying the DOM with a script that runs but throws errors like "This document requires 'TrustedHTML' assignment"

See the above points, but if it doesn't work, check if we were able to set our own custom policy, it'll be assigned to the variable TTP . Instead of using things like someDomElement.innerHTML += "<div class='myClass'><p>some <b>content</b></p></div>"; use this approach

TrustedScriptURL

The TrustedScriptURL interface of the Trusted Types API represents a string that a developer can insert into an injection sink that will parse it as a URL of an external script. These objects are created via TrustedTypePolicy.createScriptURL() and therefore have no constructor.

The value of a TrustedScriptURL object is set when the object is created and cannot be changed by JavaScript as there is no setter exposed.

Returns a JSON representation of the stored data.

A string containing the sanitized URL.

This document requires ‘TrustedScriptURL’ assignment

trustedhtml assignment

After adding require-trusted-types-for 'script'; in my Content-Security-Policy header, which introduced from Chrome 83 Beta to help lock down DOM XSS injection sinks,

when I open my website, it becomes a blank page. I got many these three kinds of errors in my console. (Chrome version 83.0.4103.61)

This document requires ‘TrustedScript’ assignment. This document requires ‘TrustedScriptURL’ assignment. TypeError: Failed to set the ‘src’ property on ‘HTMLScriptElement’: This document requires ‘TrustedScriptURL’ assignment.

I have read the article Prevent DOM-based cross-site scripting vulnerabilities with Trusted Types . However, the article only says how to handle TrustedHTML , but not TrustedScript or TrustedScriptURL .

Any guide will be helpful. Thanks!

Advertisement

We have been running into the very same problem.

Here’s how you fix it:

Install the DOMPurify library. npm install --save DOMPurify

Create a file trusted-security-policies.js .

In the entry point for your bundler (like e.g. webpack), import this file first (before any code that potentially violates the content security policy):

What this does: Whenever a string is assigned to be parsed as HTML , or as a URL, or as a script, the browser automatically passes this string through the defined handler function.

For HTML, the HTML is being sanitized from potential XSS code by the DOMPurify library.

For scriptURL and script , the string is just passed through. Please note that this effectively disables security for these two parts and should only be used for as long as you haven’t identified how to make these strings safe yourself. As soon as you have that, replace the handler functions accordingly.

Edit, December 2021: I was able to contribute to DOMPurify so the library now also can be configured to work if you have the need to use custom elements in your HTML strings, as well as custom attributes (which prior to release 2.3.4 were simply removed in the sanitization process):
