QID 980213: Nodejs (npm) Security Update for graphql-playground-html (GHSA-4852-vrh7-28rf)

Security update has been released for graphql-playground-html to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

**directly impacted:**

- `graphql-playground-html@<1.6.22` - all unsanitized user input for `renderPlaygroundPage()`

**all of our consuming packages** of `graphql-playground-html` are impacted:

- `graphql-playground-middleware-express@<1.7.16` - unsanitized user input to `expressPlayground()`
- `graphql-playground-middleware-koa@<1.6.15` - unsanitized user input to `koaPlayground()`
- `graphql-playground-middleware-lambda@<1.7.17` - unsanitized user input to `lambdaPlayground()`
- `graphql-playground-middleware-hapi@<1.6.13` - unsanitized user input to `hapiPlayground()`

as well as ***any other packages*** that use these methods with unsanitized user input.

**not impacted:**

- `graphql-playground-electron` - uses `renderPlaygroundPage()` statically for a webpack build for electron bundle, no dynamic user input
- `graphql-playground-react` - usage of the component directly in a react application does not expose reflected XSS vulnerabilities. only the demo in `public/` contains the vulnerability, because it uses an old version of the html pacakge.

  • CVSS V3 rated as High - 7.4 severity.
  • CVSS V2 rated as Medium - 4.3 severity.
  • Solution
    upgrading to the above mentioned versions will solve the issue.

    If you're using `graphql-playground-html` directly, then:

    ```
    yarn add graphql-playground-html@^1.6.22
    ```

    or

    ```
    npm install --save graphql-playground-html@^1.6.22
    ```

    Then, similar steps need to be taken for each middleware:

    - [Upgrade Express Middleware](https://www.npmjs.com/package/graphql-playground-middleware-express#security-upgrade-steps)
    - [Upgrade Koa Middleware](https://www.npmjs.com/package/graphql-playground-middleware-koa#security-upgrade-steps)
    - [Upgrade Lambda Middleware](https://www.npmjs.com/package/graphql-playground-middleware-lambda#security-upgrade-steps)
    - [Upgrade Hapi Middleware](https://www.npmjs.com/package/graphql-playground-middleware-hapi#security-upgrade-steps)Workaround:
    Ensure you properly sanitize *all* user input for options you use for whatever function to initialize GraphQLPlayground:

    for example, with `graphql-playground-html` and express:

    ```js
    const { sanitizeUrl } = require('@braintree/sanitize-url');

    const qs = require('querystringify');

    const { renderPlaygroundPage } = require('graphql-playground-html');

    module.exports = (req, res, next) => {
    const { endpoint } = qs.parse(req.url)
    res.html(renderPlaygroundPage({endpoint: sanitizeUrl(endpoint) })).status(200)
    next()
    }
    ```

    or, with `graphql-playground-express`:

    ```js
    const { expressPlayground } = require('graphql-playground-middleware-express');
    const { sanitizeUrl } = require('@braintree/sanitize-url');

    const qs = require('querystringify');

    const { renderPlaygroundPage } = require('graphql-playground-html');

    module.exports = (req, res, next) => {
    const { endpoint } = qs.parse(req.url)
    res.html(expressPlayground({endpoint: sanitizeUrl(endpoint) })).status(200)
    next()
    }
    ```
