GitHub Vulnerability Alerts

CVE-2024-56140

Summary

A bug in Astro’s CSRF-protection middleware allows requests to bypass CSRF checks.

Details

When the security.checkOrigin configuration option is set to true, Astro middleware will perform a CSRF check. (Source code: https://github.com/withastro/astro/blob/6031962ab5f56457de986eb82bd24807e926ba1b/packages/astro/src/core/app/middlewares.ts)

For example, with the following Astro configuration:

// astro.config.mjs
import { defineConfig } from 'astro/config';
import node from '@​astrojs/node';

export default defineConfig({
	output: 'server',
	security: { checkOrigin: true },
	adapter: node({ mode: 'standalone' }),
});

A request like the following would be blocked if made from a different origin:

// fetch API or <form action="https://test.example.com/" method="POST">
fetch('https://test.example.com/', {
	method: 'POST',
	credentials: 'include',
	body: 'a=b',
	headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
});
// => Cross-site POST form submissions are forbidden

However, a vulnerability exists that can bypass this security.

Pattern 1: Requests with a semicolon after the Content-Type

A semicolon-delimited parameter is allowed after the type in Content-Type.

Web browsers will treat a Content-Type such as application/x-www-form-urlencoded; abc as a simple request and will not perform preflight validation. In this case, CSRF is not blocked as expected.

fetch('https://test.example.com', {
	method: 'POST',
	credentials: 'include',
	body: 'test',
	headers: { 'Content-Type': 'application/x-www-form-urlencoded; abc' },
});
// => Server-side functions are executed (Response Code 200).

Pattern 2: Request without Content-Type header

The Content-Type header is not required for a request. The following examples are sent without a Content-Type header, resulting in CSRF.

// Pattern 2.1 Request without body
fetch('http://test.example.com', { method: 'POST', credentials: 'include' });

// Pattern 2.2 Blob object without type
fetch('https://test.example.com', {
	method: 'POST',
	credentials: 'include',
	body: new Blob(['a=b'], {}),
});

Impact

Bypass CSRF protection implemented with CSRF middleware.

Note

Even with credentials: 'include', browsers may not send cookies due to third-party cookie blocking. This feature depends on the browser version and settings, and is for privacy protection, not as a CSRF measure.

CVE-2024-56159

Summary

A bug in the build process allows any unauthenticated user to read parts of the server source code.

Details

During build, along with client assets such as css and font files, the sourcemap files for the server code are moved to a publicly-accessible folder.
https://github.com/withastro/astro/blob/176fe9f113fd912f9b61e848b00bbcfecd6d5c2c/packages/astro/src/core/build/static-build.ts#L139

Any outside party can read them with an unauthorized HTTP GET request to the same server hosting the rest of the website.

While some server files are hashed, making their access obscure, the files corresponding to the file system router (those in src/pages) are predictably named. For example. the sourcemap file for src/pages/index.astro gets named dist/client/pages/index.astro.mjs.map.

PoC

Here is one example of an affected open-source website:
https://creatorsgarten.org/pages/index.astro.mjs.map

The file can be saved and opened using https://evanw.github.io/source-map-visualization/ to reconstruct the source code.

The above accurately mirrors the source code as seen in the repository: https://github.com/creatorsgarten/creatorsgarten.org/blob/main/src/pages/index.astro

The above was found as the 4th result (and the first one on Astro 5.0+) when making the following search query on GitHub.com (search results link):

path:astro.config.mjs @&#8203;sentry/astro

This vulnerability is the root cause of https://github.com/withastro/astro/issues/12703, which links to a simple stackblitz project demonstrating the vulnerability. Upon build, notice the contents of the dist/client (referred to as config.build.client in astro code) folder. All astro servers make the folder in question accessible to the public internet without any authentication. It contains .map files corresponding to the code that runs on the server.

Impact

All server-output (SSR) projects on Astro 5 versions v5.0.3 through v5.0.6 (inclusive), that have sourcemaps enabled, either directly or through an add-on such as sentry, are affected. The fix for server-output projects was released in [email protected].

Additionally, all static-output (SSG) projects built using Astro 4 versions 4.16.17 or older, or Astro 5 versions 5.0.7 or older, that have sourcemaps enabled are also affected. The fix for static-output projects was released in [email protected], and backported to Astro v4 in [email protected].

The immediate impact is limited to source code. Any secrets or environment variables are not exposed unless they are present verbatim in the source code.

There is no immediate loss of integrity within the the vulnerable server. However, it is possible to subsequently discover another vulnerability via the revealed source code .

There is no immediate impact to availability of the vulnerable server. However, the presence of an unsafe regular expression, for example, can quickly be exploited to subsequently compromise the availability.

  • Network attack vector.
  • Low attack complexity.
  • No privileges required.
  • No interaction required from an authorized user.
  • Scope is limited to first party. Although the source code of closed-source third-party software may also be exposed.

Remediation

The fix for server-output projects was released in [email protected], and the fix for static-output projects was released in [email protected] and backported to Astro v4 in [email protected]. Users are advised to update immediately if they are using sourcemaps or an integration that enables sourcemaps.

  • #​12227 8b1a641 Thanks @​florian-lefebvre! - Fixes a case where environment variables would not be refreshed when using astro:env

  • #​12239 2b6daa5 Thanks @​ematipico! - BREAKING CHANGE to the experimental Container API only

    Changes the default page rendering behavior of Astro components in containers, and adds a new option partial: false to render full Astro pages as before.

    Previously, the Container API was rendering all Astro components as if they were full Astro pages containing <!DOCTYPE html> by default. This was not intended, and now by default, all components will render as page partials: only the contents of the components without a page shell.

    To render the component as a full-fledged Astro page, pass a new option called partial: false to renderToString() and renderToResponse():

    import { experimental_AstroContainer as AstroContainer } from 'astro/container';
import Card from '../src/components/Card.astro';

const container = AstroContainer.create();

await container.renderToString(Card); // the string will not contain `<!DOCTYPE html>`
await container.renderToString(Card, { partial: false }); // the string will contain `<!DOCTYPE html>`

  • #​12177 a4ffbfa Thanks @​matthewp! - Ensure we target scripts for execution in the router

Minor Changes

  • #​12039 710a1a1 Thanks @​ematipico! - Adds a markdown.shikiConfig.langAlias option that allows aliasing a non-supported code language to a known language. This is useful when the language of your code samples is not a built-in Shiki language, but you want your Markdown source to contain an accurate language while also displaying syntax highlighting.

    The following example configures Shiki to highlight cjs code blocks using the javascript syntax highlighter:

    import { defineConfig } from 'astro/config';

export default defineConfig({
  markdown: {
    shikiConfig: {
      langAlias: {
        cjs: 'javascript',
      },
    },
  },
});

    Then in your Markdown, you can use the alias as the language for a code block for syntax highlighting:

    ```cjs
'use strict';

function commonJs() {
  return 'I am a commonjs file';
}
```

  • #​11984 3ac2263 Thanks @​chaegumi! - Adds a new build.concurreny configuration option to specify the number of pages to build in parallel

    In most cases, you should not change the default value of 1.

    Use this option only when other attempts to reduce the overall rendering time (e.g. batch or cache long running tasks like fetch calls or data access) are not possible or are insufficient.

    Use this option only if the refactors are not possible. If the number is set too high, the page rendering may slow down due to insufficient memory resources and because JS is single-threaded.

    [!WARNING]
    This feature is stable and is not considered experimental. However, this feature is only intended to address difficult performance issues, and breaking changes may occur in a minor release to keep this option as performant as possible.

    // astro.config.mjs
import { defineConfig } from 'astro';

export default defineConfig({
  build: {
    concurrency: 2,
  },
});
Patch Changes

  • #​12160 c6fd1df Thanks @​louisescher! - Fixes a bug where astro.config.mts and astro.config.cts weren't reloading the dev server upon modifications.

  • #​12130 e96bcae Thanks @​thehansys! - Fixes a bug in the parsing of x-forwarded-\* Request headers, where multiple values assigned to those headers were not correctly parsed.

    Now, headers like x-forwarded-proto: https,http are correctly parsed.

  • #​12147 9db755a Thanks @​ascorbic! - Skips setting statusMessage header for HTTP/2 response

    HTTP/2 doesn't support status message, so setting this was logging a warning.

  • #​12151 bb6d37f Thanks @​ematipico! - Fixes an issue where Astro.currentLocale wasn't incorrectly computed when the defaultLocale belonged to a custom locale path.

  • #​12105 42037f3 Thanks @​ascorbic! - Returns custom statusText that has been set in a Response

  • #​12109 ea22558 Thanks @​ematipico! - Fixes a regression that was introduced by an internal refactor of how the middleware is loaded by the Astro application. The regression was introduced by #​11550.

    When the edge middleware feature is opted in, Astro removes the middleware function from the SSR manifest, and this wasn't taken into account during the refactor.

  • #​12038 26ea5e8 Thanks @​ascorbic! - Resolves image paths in content layer with initial slash as project-relative

    When using the image() schema helper, previously paths with an initial slash were treated as public URLs. This was to match the behavior of markdown images. However this is a change from before, where paths with an initial slash were treated as project-relative. This change restores the previous behavior, so that paths with an initial slash are treated as project-relative.

  • #​11939 7b09c62 Thanks @​bholmesdev! - Adds support for Zod discriminated unions on Action form inputs. This allows forms with different inputs to be submitted to the same action, using a given input to decide which object should be used for validation.

    This example accepts either a create or update form submission, and uses the type field to determine which object to validate against.

    import { defineAction } from 'astro:actions';
import { z } from 'astro:schema';

export const server = {
  changeUser: defineAction({
    accept: 'form',
    input: z.discriminatedUnion('type', [
      z.object({
        type: z.literal('create'),
        name: z.string(),
        email: z.string().email(),
      }),
      z.object({
        type: z.literal('update'),
        id: z.number(),
        name: z.string(),
        email: z.string().email(),
      }),
    ]),
    async handler(input) {
      if (input.type === 'create') {
        // input is { type: 'create', name: string, email: string }
      } else {
        // input is { type: 'update', id: number, name: string, email: string }
      }
    },
  }),
};

    The corresponding create and update forms may look like this:

Patch Changes

  • #​11879 bd1d4aa Thanks @​matthewp! - Allow passing a cryptography key via ASTRO_KEY

    For Server islands Astro creates a cryptography key in order to hash props for the islands, preventing accidental leakage of secrets.

    If you deploy to an environment with rolling updates then there could be multiple instances of your app with different keys, causing potential key mismatches.

    To fix this you can now pass the ASTRO_KEY environment variable to your build in order to reuse the same key.

    To generate a key use:

    astro create-key

    This will print out an environment variable to set like:

    ASTRO_KEY=PIAuyPNn2aKU/bviapEuc/nVzdzZPizKNo3OqF/5PmQ=

Minor Changes

  • #​11729 1c54e63 Thanks @​ematipico! - Adds a new variant sync for the astro:config:setup hook's command property. This value is set when calling the command astro sync.

    If your integration previously relied on knowing how many variants existed for the command property, you must update your logic to account for this new option.

  • #​11743 cce0894 Thanks @​ph1p! - Adds a new, optional property timeout for the client:idle directive.

    This value allows you to specify a maximum time to wait, in milliseconds, before hydrating a UI framework component, even if the page is not yet done with its initial load. This means you can delay hydration for lower-priority UI elements with more control to ensure your element is interactive within a specified time frame.

    <ShowHideButton client:idle={{ timeout: 500 }} />

  • #​11677 cb356a5 Thanks @​ematipico! - Adds a new option fallbackType to i18n.routing configuration that allows you to control how fallback pages are handled.

    When i18n.fallback is configured, this new routing option controls whether to redirect to the fallback page, or to rewrite the fallback page's content in place.

    The "redirect" option is the default value and matches the current behavior of the existing fallback system.

    The option "rewrite" uses the new rewriting system to create fallback pages that render content on the original, requested URL without a browser refresh.

    For example, the following configuration will generate a page /fr/index.html that will contain the same HTML rendered by the page /en/index.html when src/pages/fr/index.astro does not exist.

    // astro.config.mjs
export default defineConfig({
  i18n: {
    locals: ['en', 'fr'],
    defaultLocale: 'en',
    routing: {
      prefixDefaultLocale: true,
      fallbackType: 'rewrite',
    },
    fallback: {
      fr: 'en',
    },
  },
});

  • #​11708 62b0d20 Thanks @​martrapp! - Adds a new object swapFunctions to expose the necessary utility functions on astro:transitions/client that allow you to build custom swap functions to be used with view transitions.

    The example below uses these functions to replace Astro's built-in default swap function with one that only swaps the <main> part of the page:

    <script>
  import { swapFunctions } from 'astro:transitions/client';

  document.addEventListener('astro:before-swap', (e) => { e.swap = () => swapMainOnly(e.newDocument) });

  function swapMainOnly(doc: Document) {
    swapFunctions.deselectScripts(doc);
    swapFunctions.swapRootAttributes(doc);
    swapFunctions.swapHeadElements(doc);
    const restoreFocusFunction = swapFunctions.saveFocus();
    const newMain = doc.querySelector('main');
