CVE-2021-41248 (published 2021-11-04T21:15Z)

GraphiQL is the reference implementation of this monorepo, GraphQL IDE, an official project under the GraphQL Foundation. All versions of graphiql older than graphiql@1.4.7 are vulnerable to compromised HTTP schema introspection responses or schema prop values with malicious GraphQL type names, exposing a dynamic XSS attack surface that can allow code injection on operation autocomplete. In order for the attack to take place, the user must load a vulnerable schema in graphiql. There are a number of ways that can occur. By default, the schema URL is not attacker-controllable in graphiql or in its suggested implementations or examples, leaving only very complex attack vectors. If a custom implementation of graphiql's fetcher allows the schema URL to be set dynamically, such as a URL query parameter like ?endpoint= in graphql-playground, or a database provided value, then this custom graphiql implementation is vulnerable to phishing attacks, and thus much more readily available, low or no privelege level xss attacks. The URLs could look like any generic looking graphql schema URL. It should be noted that desktop clients such as Altair, Insomnia, Postwoman, do not appear to be impacted by this. This vulnerability does not impact codemirror-graphql, monaco-graphql or other dependents, as it exists in onHasCompletion.ts in graphiql. It does impact all forks of graphiql, and every released version of graphiql.

cwe_name: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
description: The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
extended_description: 
            Cross-site scripting (XSS) vulnerabilities occur when:
            
               Untrusted data enters a web application, typically from a web request.
               The web application dynamically generates a web page that contains this untrusted data.
               During page generation, the application does not prevent the data from containing content that is executable by a web browser, such as JavaScript, HTML tags, HTML attributes, mouse events, Flash, ActiveX, etc.
               A victim visits the generated web page through a web browser, which contains malicious script that was injected using the untrusted data.
               Since the script comes from a web page that was sent by the web server, the victim's web browser executes the malicious script in the context of the web server's domain.
               This effectively violates the intention of the web browser's same-origin policy, which states that scripts in one domain should not be able to access resources or run code in a different domain.
            
            There are three main kinds of XSS:
            
               
                  Type 1: Reflected XSS (or Non-Persistent) - 
         			The server reads data directly from the HTTP request and reflects it back in the HTTP response. Reflected XSS exploits occur when an attacker causes a victim to supply dangerous content to a vulnerable web application, which is then reflected back to the victim and executed by the web browser. The most common mechanism for delivering malicious content is to include it as a parameter in a URL that is posted publicly or e-mailed directly to the victim. URLs constructed in this manner constitute the core of many phishing schemes, whereby an attacker convinces a victim to visit a URL that refers to a vulnerable site. After the site reflects the attacker's content back to the victim, the content is executed by the victim's browser.
               
                  Type 2: Stored XSS (or Persistent) - 
               The application stores dangerous data in a database, message forum, visitor log, or other trusted data store. At a later time, the dangerous data is subsequently read back into the application and included in dynamic content. From an attacker's perspective, the optimal place to inject malicious content is in an area that is displayed to either many users or particularly interesting users. Interesting users typically have elevated privileges in the application or interact with sensitive data that is valuable to the attacker. If one of these users executes malicious content, the attacker may be able to perform privileged operations on behalf of the user or gain access to sensitive data belonging to the user. For example, the attacker might inject XSS into a log message, which might not be handled properly when an administrator views the logs.
            
               
                  Type 0: DOM-Based XSS - 
               In DOM-based XSS, the client performs the injection of XSS into the page; in the other types, the server performs the injection. DOM-based XSS generally involves server-controlled, trusted script that is sent to the client, such as Javascript that performs sanity checks on a form before the user submits it. If the server-supplied script processes user-supplied data and then injects it back into the web page (such as with dynamic HTML), then DOM-based XSS is possible.
            
            
            Once the malicious script is injected, the attacker can perform a variety of malicious activities. The attacker could transfer private information, such as cookies that may include session information, from the victim's machine to the attacker. The attacker could send malicious requests to a web site on behalf of the victim, which could be especially dangerous to the site if the victim has administrator privileges to manage that site. Phishing attacks could be used to emulate trusted web sites and trick the victim into entering a password, allowing the attacker to compromise the victim's account on that web site. Finally, the script could exploit a vulnerability in the web browser itself possibly taking over the victim's machine, sometimes referred to as "drive-by hacking."
            In many cases, the attack can be launched without the victim even being aware of it. Even with careful users, attackers frequently use a variety of methods to encode the malicious portion of the attack, such as URL encoding or Unicode, so the request looks less suspicious.

This change fixes an XSS vulnerability that has been present since the first
commit of GraphiQL when used with an untrusted GraphQL server. It applies three
strategies to fix via defense-in-depth: HTML escaping a string in a contexts
that uses innerHTML; validating incoming schemas with graphql-js validateSchema;
and updating markdown-it to the latest version.

See docs/security/2021-introspection-schema-xss.md for more details.

+
+## 1. GraphiQL introspection schema template injection attack: Advisory Statement
+
+This is a security advisory for an XSS vulnerability in `graphiql`.
+
+A similar vulnerability affects `graphql-playground`, a fork of `graphiql`. There is a corresponding `graphql-playground` [advisory](https://github.com/graphql/graphql-playground/security/advisories/GHSA-59r9-6jp6-jcm7) and [Apollo Server advisory](https://github.com/apollographql/apollo-server/security/advisories/GHSA-qm7x-rc44-rrqw).
+
+### 1.1. Impact
+
+All versions of `graphiql` older than [`graphiql@1.4.3`](https://github.com/graphql/graphiql/releases/tag/v1.4.3) are vulnerable to compromised HTTP schema introspection responses or `schema` prop values with malicious GraphQL type names, exposing a dynamic XSS attack surface that can allow code injection on operation autocomplete.
+
+In order for the attack to take place, the user must load a vulnerable schema in `graphiql`. There are a number of ways that can occur.
+
+By default, the schema URL is _not_ attacker-controllable in `graphiql` or in its suggested implementations or examples, leaving only very complex attack vectors.
+
+If a custom implementation of `graphiql`'s `fetcher` allows the schema URL to be set dynamically, such as a URL query parameter like `?endpoint=` in `graphql-playground`, or a database provided value, then this custom `graphiql` implementation is _vulnerable to phishing attacks_, and thus much more readily available, low or no privelege level xss attacks. The URLs could look like any generic looking graphql schema URL.
+
+Because this exposes an XSS attack surface, it would be possible for a threat actor to exfiltrate user credentials, data, etc. using arbitrary malicious scripts, without it being known to the user.
+
+### 1.2. Scope
+
+This advisory describes the impact on the `graphiql` package. The vulnerability also affects other projects forked from `graphiql` such as [`graphql-playground`](https://github.com/graphql/graphql-playground/security/advisories/GHSA-59r9-6jp6-jcm7) and the `graphql-playground` fork distributed by Apollo Server. The impact is more severe in the `graphql-playground` implementations; see the [`graphql-playground` advisory](https://github.com/graphql/graphql-playground/security/advisories/GHSA-59r9-6jp6-jcm7) and [Apollo Server advisory](https://github.com/apollographql/apollo-server/security/advisories/GHSA-qm7x-rc44-rrqw) for details.
+
+This vulnerability does not impact `codemirror-graphql`, `monaco-graphql` or other dependents, as it exists in `onHasCompletion.ts` in `graphiql`. It does impact all forks of `graphiql`, and every released version of `graphiql`.
+
+It should be noted that desktop clients such as Altair, Insomnia, Postwoman, do not appear to be impacted by this.
+
+### 1.3. Patches
+
+`graphiql@1.4.3` addresses this issue via defense in depth.
+
+- **HTML-escaping text** that should be treated as text rather than HTML. In most of the app, this happens automatically because React escapes all interpolated text by default. However, one vulnerable component uses the unsafe `innerHTML` API and interpolated type names directly into HTML. We now properly escape that type name, which fixes the known vulnerability.
+
+- **Validates the schema** upon receiving the introspection response or schema changes. Schemas with names that violate the GraphQL spec will no longer be loaded. (This includes preventing the Doc Explorer from loading.) This change is also sufficient to fix the known vulnerability. You can disable this validation by setting `dangerouslyAssumeSchemaIsValid={true}`, which means you are relying only on escaping values to protect you from this attack.
+
+- **Ensuring that user-generated HTML is safe**. Schemas can contain Markdown in `description` and `deprecationReason` fields, and the web app renders them to HTML using the `markdown-it` library. As part of the development of `graphiql@1.4.3`, we verified that our use of `markdown-it` prevents the inclusion of arbitrary HTML. We use `markdown-it` without setting `html: true`, so we are comfortable relying on [`markdown-it`'s HTML escaping](https://github.com/markdown-it/markdown-it/blob/master/docs/security.md) here. We considered running a second level of sanitization over all rendered Markdown using a library such as `dompurify` but believe that is unnecessary as `markdown-it`'s sanitization appears to be adequate. `graphiql@1.4.3` does update to the latest version of `markdown-it` (v12, from v10) so that any security fixes in v11 and v12 will take effect.
+
+### 1.3.1 CDN bundle implementations may be automatically patched
+
+Note that if your implementation is depending on a CDN version of `graphiql`, and is pointed to the `latest` tag (usually the default for most cdns if no version is specified) then this issue is already mitigated, in case you were vulnerable to it before.
+
+### 1.4. Workarounds for Older Versions
+
+If you cannot use `graphiql@1.4.3` or later
+
+- Always use a static URL to a trusted server that is serving a trusted GraphQL schema.
+
+- If you have a custom implementation that allows using user-provided schema URLs via a query parameter, database value, etc, you must either disable this customization, or only allow trusted URLs.
+
+### 1.5. How to Re-create the Exploit
+
+You can see an example on [codesandbox](https://codesandbox.io/s/graphiql-xss-exploit-gr22f?file=/src/App.js). These are both fixed to the last `graphiql` release `1.4.2` which is the last vulnerable release; however it would work with any previous release of `graphiql`.
+
+Both of these examples are meant to demonstrate the phishing attack surface, so they are customized to accept a `url` parameter. To demonstrate the phishing attack, add `?url=https://graphql-xss-schema.netlify.app/graphql` to the in-codesandbox browser.
+
+Erase the contents of the given query and type `{u`. You will see an alert window open, showing that attacker-controlled code was executed.
+
+Note that when React is in development mode, a validation exception is thrown visibly; however that exception is usually buried in the browser console in a production build of `graphiql`. This validation exception comes from `getDiagnostics`, which invokes `graphql` `validate()` which in turn will `assertValidSchema()`, as `apollo-server-core` does on executing each operation. This validation does not prevent the exploit from being successful.
+
+Note that something like the `url` parameter is not required for the attack to happen if `graphiql`'s `fetcher` is configured in a different way to communicate with a compromised GraphQL server.

+### 1.8. For more information
+
+If you have any questions or comments about this advisory:
+
+- Open an issue in [graphiql repo](https://github.com/graphql/graphiql/new/issues)
+
+## 2. More Details on the Vulnerability
+
+This section provides more details in addition to the advisory.
+
+An installation of the GraphiQL web app is vulnerable if two conditions are met:
+
+- The web app trusts information from its corresponding GraphQL server by interpolating information such as GraphQL type names directly into HTML instead of appropriately escaping or sanitizing the information.
+- The victim can load the web app in a way where it speaks to a GraphQL server controlled by the attacker.
+
+All versions of `graphiql` prior to 1.4.3 inappropriately trust type names provided by the GraphQL server. They additionally rely on XSS filtering in the `markdown-it` package to try to protect themselves from XSS attacks in GraphQL descriptions and deprecation reasons.
+
+By default, `graphiql` does _not_ allow the attacker to control what GraphQL server it speaks to. Therefore, many installations of `graphiql` are not affected by this advisory. Installations are only affected if the `fetcher` argument provided to GraphiQL allows arbitrary customization of the GraphQL endpoint (eg, reading a GraphQL URL from an URL parameter), or if the attacker has another way of affecting the introspection schema returned by the GraphQL server. (Note that `graphql-playground`, a project which started as a fork of `graphiql`, does this sort of URL parsing by default, so `graphql-playground` installations _are_ affected by a corresponding vulnerability in their default configuration.)
+
+One example of "another way of affecting the introspection schema" would be if you served `graphiql` as part of a PAAS platform that allows users to define their own GraphQL schemas. In this case, even though the `graphiql` installation might be hard-wired to a single GraphQL endpoint, the attacker has control over that GraphQL endpoint and could use it to inject scripts into `graphiql`. In this case, your `graphiql` installation could be vulnerable if it responds to introspection requests without first validating its schema. GraphQL servers can prevent this by refusing to execute operations (including introspection operations) on invalid schemas; any server built with `graphql-js` properly validates its schema prior to execution.
+
+## 3. Compromised introspection Schema Example
+
+You can view the code for the exploited schema [on codesandbox](https://codesandbox.io/s/graphql-xss-compromised-schema-3wdq7?file=/src/bad-schema.js) or [in the repository](../../packages/graphiql/test/bad-schema.js)
+
+As you can see, the introspection schema must contain items with a compromised `name` value. this could be fields, input object names, enum names, variable names, etc any graphql [NamedType](https://github.com/graphql/graphql-spec/blob/main/spec/Section%202%20--%20Language.md#type-references) in the schema with it's name rendered in the autocomplete list.
+
+```json
