The URL for this fetch is derived from `request.url`, which in turn gets its origin from the incoming `Host` header. When the `Host` header is not validated against `allowedDomains`, an attacker can point the fetch at an arbitrary host and read the response. ##### Who is affected This affects SSR deployments that: 1. Have a prerendered 404 or 500 page 2. Use `createRequestFromNodeRequest` from `astro/app/node` with `app.render()` **without** overriding `prerenderedErrorPageFetch` — this includes custom servers built on the public API and third-party adapters **Not affected:** - `@astrojs/node` >= 9.5.4 (reads error pages from disk) - `@astrojs/cloudflare` (uses the ASSETS binding) - The dev server (renders error pages in-process) ##### How it works `createRequestFromNodeRequest` builds `request.url` from the raw `Host` / `:authority` header. The `allowedDomains` option is accepted but only gates `X-Forwarded-For` — it does not constrain the URL origin. (The public `createRequest` does fall back to `localhost` for unvalidated hosts; this internal builder did not.) When `app.render()` encounters a 404 or 500 with a prerendered error route, `default-handler.ts` constructs the error page URL using the origin from `request.url` and fetches it via `prerenderedErrorPageFetch`, which defaults to global `fetch`. The response body is served to the client. An attacker sends a request with `Host: attacker-host:port`, triggers an error (e.g., requesting a nonexistent path for a 404), and receives the response from the attacker-controlled host reflected back. ##### Remediation The error page fetch origin is now validated against `allowedDomains` before use. When the host is validated, the original origin is preserved. Otherwise, it falls back to `localhost`. The fetch is also wrapped in a try/catch so that connection failures degrade gracefully to a plain error response. ##### Credit 5ud0 / Tarmo Technologies #### Severity - CVSS Score: 7.5 / 10 (High) - Vector String: `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N` #### References - [https://github.com/withastro/astro/security/advisories/GHSA-2pvr-wf23-7pc7](https://redirect.github.com/withastro/astro/security/advisories/GHSA-2pvr-wf23-7pc7) - [https://github.com/advisories/GHSA-2pvr-wf23-7pc7](https://redirect.github.com/advisories/GHSA-2pvr-wf23-7pc7) This data is provided by the [GitHub Advisory Database](https://redirect.github.com/advisories/GHSA-2pvr-wf23-7pc7) ([CC-BY 4.0](https://redirect.github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### Astro: XSS via Unescaped Attribute Names in Spread Props [CVE-2026-54298](https://nvd.nist.gov/vuln/detail/CVE-2026-54298) / [GHSA-jrpj-wcv7-9fh9](https://redirect.github.com/advisories/GHSA-jrpj-wcv7-9fh9) <details> <summary>More information</summary> #### Details ##### Summary The `spreadAttributes` function in Astro's server-side rendering pipeline iterates over object keys and passes them directly to `addAttribute`, which interpolates the key into the HTML output without escaping. When a developer uses the spread syntax `{...props}` on an HTML element and the object keys come from an untrusted source (API, CMS, URL parameters), an attacker can inject arbitrary HTML attributes including event handlers like `onmousemove`, `onclick`, or break out of the attribute context entirely to inject new elements. ##### Details The vulnerable function is [`addAttribute`](https://redirect.github.com/withastro/astro/blob/main/packages/astro/src/runtime/server/render/util.ts#L81-L141) at `packages/astro/src/runtime/server/render/util.ts:81-141`: ```javascript export function addAttribute(value: any, key: string, shouldEscape = true, tagName = '') { if (value == null) { return ''; } return markHTMLString(` ${key}="${toAttributeString(value, shouldEscape)}"`); // key interpolated not escaped } ``` This function is called from [`spreadAttributes`](https://redirect.github.com/withastro/astro/blob/main/packages/astro/src/runtime/server/index.ts#L91-L92) at `packages/astro/src/runtime/server/index.ts:91-92`: ```javascript for (const [key, value] of Object.entries(values)) { output += addAttribute(value, key, true, _name); } ``` The `toAttributeString` function escapes the attribute value, but the attribute name `key` is never validated or escaped. An attacker can craft a JSON object with a key containing " characters to break out of the attribute context and inject event handlers. Execution flow: User controlled object keys (from API, CMS, URL params) are spread onto element via `{...props}`. The compiler generates `spreadAttributes(props)` which iterates with `Object.entries()` and calls `addAttribute(value, key)`. The key is interpolated as `` ` ${key}="${escapedValue}"` ``. A malicious key breaks attribute context, resulting in XSS. ##### POC Create an SSR Astro page (`src/pages/index.astro`): ```astro --- const props = JSON.parse(Astro.url.searchParams.get('props') || '{}'); --- <html> <body> <h1>Hello</h1> <div {...props}>Move mouse here</div> </body> </html> ``` Enable SSR in `astro.config.mjs` (for URL based demo): ```javascript export default defineConfig({ output: 'server' }); ``` Note: SSR is not required for the vulnerability to exist. In static builds (default), the attack vector is compromised data sources at build time (API, CMS, database). SSR simply makes the PoC easier to demonstrate via URL parameters. Start the dev server and visit: ``` http://localhost:4321/?props={"x\" onmousemove=\"alert(document.cookie)\" y":""} ``` URL encoded: ``` http://localhost:4321/?props=%7B%22x%5C%22%20onmousemove%3D%5C%22alert(document.cookie)%5C%22%20y%22%3A%22%22%7D ``` View the HTML source. The output contains: ```html <div x" onmousemove="alert(document.cookie)" y="">Move mouse here</div> ``` The key `x" onmousemove="alert(document.cookie)" y` breaks out of the attribute context. Moving the mouse over the div executes the JavaScript. <img width="1919" height="992" alt="Captura de tela 2026-06-02 005906" src="https://github.com/user-attachments/assets/ef69c12e-7edf-472e-97d1-3dfa540e61b4" /> ##### Impact An attacker can execute arbitrary JavaScript in the context of a victim's browser session on any Astro application that spreads object props from untrusted sources onto HTML elements. This is a common pattern when integrating with external APIs or CMS systems. Exploitation enables session hijacking via cookie theft, credential theft by injecting fake login forms or keyloggers, defacement of the rendered page, and redirection to attacker controlled domains. The vulnerability affects all Astro versions that support spread syntax on HTML elements and is exploitable in SSR, SSG (if build time data is compromised), and hybrid deployments. #### Severity - CVSS Score: 4.2 / 10 (Medium) - Vector String: `CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N` #### References - [https://github.com/withastro/astro/security/advisories/GHSA-jrpj-wcv7-9fh9](https://redirect.github.com/withastro/astro/security/advisories/GHSA-jrpj-wcv7-9fh9) - [https://github.com/advisories/GHSA-jrpj-wcv7-9fh9](https://redirect.github.com/advisories/GHSA-jrpj-wcv7-9fh9) This data is provided by the [GitHub Advisory Database](https://redirect.github.com/advisories/GHSA-jrpj-wcv7-9fh9) ([CC-BY 4.0](https://redirect.github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### Release Notes <details> <summary>withastro/astro (astro)</summary> ### [`v6.4.6`](https://redirect.github.com/withastro/astro/blob/HEAD/packages/astro/CHANGELOG.md#646) [Compare Source](https://redirect.github.com/withastro/astro/compare/astro@6.4.5...astro@6.4.6) ##### Patch Changes - [#16765](https://redirect.github.com/withastro/astro/pull/16765) [`b10e86e`](https://redirect.github.com/withastro/astro/commit/b10e86e6dbaf04678127c86366befc0b78a164f6) Thanks [@fkatsuhiro](https://redirect.github.com/fkatsuhiro)! - Fixes an issue where renaming an image file while the dev server is running triggers a build error.

In production builds with `@astrojs/node` adapter, if `[a_prebuild].astro` (prerender=true) came before `[b_ssr].astro` alphabetically, requests to URLs not in the prerendered route's static paths would 404 instead of falling through to the SSR route. The fix adds fallthrough logic so that when a prerendered dynamic route matches but can't serve the request, Astro tries subsequent matching routes. ### [`v6.4.1`](https://redirect.github.com/withastro/astro/blob/HEAD/packages/astro/CHANGELOG.md#641) ##### Patch Changes - [#16883](https://redirect.github.com/withastro/astro/pull/16883) [`eeb064c`](https://redirect.github.com/withastro/astro/commit/eeb064ca9452fd9d0ad9b7557059a646a90a3e57) Thanks [@Princesseuh](https://redirect.github.com/Princesseuh)! - Restores the `astro/jsx/rehype.js` entry point so that older versions of `@astrojs/mdx` continue to work when used with Astro 6.x.

This is useful for adapters that require a consistent `dist/client/` and `dist/server/` layout regardless of build output type. ```js setAdapter({ name: 'my-adapter', adapterFeatures: { buildOutput, preserveBuildClientDir: true, preserveBuildServerDir: true, }, }); ``` - [#16848](https://redirect.github.com/withastro/astro/pull/16848) [`f732f3c`](https://redirect.github.com/withastro/astro/commit/f732f3cc716342a63e5b03815243ba10964b89dc) Thanks [@Princesseuh](https://redirect.github.com/Princesseuh)! - Adds a new `markdown.processor` configuration option, allowing you to choose an alternative Markdown processor. Websites with many Markdown/MDX files tend to be slow to build because the unified ecosystem (e.g., remark, rehype) is slow to process. This feature introduces the ability to replace this part of the build pipeline with another processor. The default processor is `unified()`. This means that existing configurations remain unchanged and your remark/rehype plugins continue to work. ```js // astro.config.mjs import { defineConfig } from 'astro/config'; import { unified } from '@astrojs/markdown-remark'; import remarkToc from 'remark-toc'; export default defineConfig({ markdown: { processor: unified({ remarkPlugins: [remarkToc], }), }, }); ``` In addition to this new configuration option, Astro provides a new alternative processor based on Rust: [Sätteri](https://satteri.bruits.org/). You can choose to use it now by installing `@astrojs/markdown-satteri`, importing the `satteri()` processor, and adapting your existing configuration: ```js // astro.config.mjs import { defineConfig } from 'astro/config'; import { satteri } from '@astrojs/markdown-satteri'; export default defineConfig({ markdown: { processor: satteri({ features: { directive: true }, }), }, }); ``` This processor does not support the remark and rehype plugins. This means you may need to convert them to [MDAST or HAST plugins](https://satteri.bruits.org/docs/plugins/) to retain your current functionality. The existing top-level `markdown.remarkPlugins`, `markdown.rehypePlugins`, `markdown.remarkRehype`, `markdown.gfm`, and `markdown.smartypants` options still work, but are now deprecated and will be removed in a future major update. The matching `remarkPlugins`, `rehypePlugins`, and `remarkRehype` options on the MDX integration are also deprecated for the same reason. To anticipate their removal, move them onto `unified({...})` (or your preferred plugin processor) : ```diff // astro.config.mjs import { defineConfig } from 'astro/config'; import remarkToc from 'remark-toc'; import rehypeSlug from 'rehype-slug'; + import { unified } from '@astrojs/markdown-remark'; export default defineConfig({ markdown: { + processor: unified({ + remarkPlugins: [remarkToc], + rehypePlugins: [rehypeSlug], + remarkRehype: true, + gfm: true, + smartypants: true, + }), - remarkPlugins: [remarkToc], - rehypePlugins: [rehypeSlug], - remarkRehype: true, - gfm: true, - smartypants: true, }, }); ``` For more information on enabling and using this feature in your project, see our [Markdown guide](https://docs.astro.build/en/guides/markdown-content/). To give feedback on this new Rust processor, see the [Native Markdown / MDX parsing and processing RFC](https://redirect.github.com/withastro/roadmap/pull/1364). ##### Patch Changes - [#16468](https://redirect.github.com/withastro/astro/pull/16468) [`4cff3a1`](https://redirect.github.com/withastro/astro/commit/4cff3a107c3750ab5f0878a6b41836705282b771) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Skips the static preview server when an adapter provides its own `previewEntrypoint`, allowing the adapter to handle both static and dynamic routes - [#16811](https://redirect.github.com/withastro/astro/pull/16811) [`e0e26db`](https://redirect.github.com/withastro/astro/commit/e0e26dbfe95f9d42f51ad414dbe877e60cbc637d) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes `X-Forwarded-Host` and `X-Forwarded-Proto` headers being ignored when set in a custom `src/app.ts` fetch handler before creating `FetchState` - [#16468](https://redirect.github.com/withastro/astro/pull/16468) [`4cff3a1`](https://redirect.github.com/withastro/astro/commit/4cff3a107c3750ab5f0878a6b41836705282b771) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes the static preview server to respect `preserveBuildClientDir`, serving files from `build.client` instead of `outDir` when the adapter requires it - [#16770](https://redirect.github.com/withastro/astro/pull/16770) [`1e2aa11`](https://redirect.github.com/withastro/astro/commit/1e2aa11caf8e7a48f37dd614fd2d4c15cc7a8439) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes a race condition where the Vite dep optimizer could lose React dependencies in dev mode when using Astro Actions - [#16468](https://redirect.github.com/withastro/astro/pull/16468) [`4cff3a1`](https://redirect.github.com/withastro/astro/commit/4cff3a107c3750ab5f0878a6b41836705282b771) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Exempts internal routes (e.g. server islands) from `getStaticPaths()` validation, fixing server island rendering on static sites - [#16468](https://redirect.github.com/withastro/astro/pull/16468) [`4cff3a1`](https://redirect.github.com/withastro/astro/commit/4cff3a107c3750ab5f0878a6b41836705282b771) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes preview for static sites that contain non-prerendered routes. Previously, the preview command ignored SSR routes discovered during route scanning and always used the static preview server. - Updated dependencies \[[`f732f3c`](https://redirect.github.com/withastro/astro/commit/f732f3cc716342a63e5b03815243ba10964b89dc), [`f732f3c`](https://redirect.github.com/withastro/astro/commit/f732f3cc716342a63e5b03815243ba10964b89dc)]: - [@astrojs/internal-helpers](https://redirect.github.com/astrojs/internal-helpers)@0.10.0 - [@astrojs/markdown-remark](https://redirect.github.com/astrojs/markdown-remark)@7.2.0 ### [`v6.3.8`](https://redirect.github.com/withastro/astro/blob/HEAD/packages/astro/CHANGELOG.md#638) [Compare Source](https://redirect.github.com/withastro/astro/compare/astro@6.3.7...astro@6.3.8) ##### Patch Changes - [#16830](https://redirect.github.com/withastro/astro/pull/16830) [`f2bf3cb`](https://redirect.github.com/withastro/astro/commit/f2bf3cb257788ff657ffbe9044fe6225e6662cb7) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes 404s for dynamically imported JS chunks when using an adapter with `assetQueryParams` (e.g. Vercel skew protection) - [#16831](https://redirect.github.com/withastro/astro/pull/16831) [`ace96ba`](https://redirect.github.com/withastro/astro/commit/ace96ba5024129cbeb9d8e75134f4f8bdf42a57a) Thanks [@astrobot-houston](https://redirect.github.com/astrobot-houston)! - Fixes a misleading `GetStaticPathsRequired` error when a redirect is configured from a dynamic route to a static (or less-dynamic) destination. For example, `'/project/[slug]': '/'` previously produced a confusing error pointing at `index.astro`. Astro now detects the parameter mismatch at config validation time and throws a clear `InvalidRedirectDestination` error naming the missing parameters. - [#16702](https://redirect.github.com/withastro/astro/pull/16702) [`b7d1758`](https://redirect.github.com/withastro/astro/commit/b7d1758efbe0544520b4b15577d2e0dd944bf8a1) Thanks [@matthewp](https://redirect.github.com/matthewp)! - Fixes scoped styles from `.astro` components being dropped when rendered inside MDX content (`<Content />` from `render(entry)`) passed through a named slot using `<Fragment slot="X">`. The Fragment component now eagerly evaluates its slot contents to ensure propagating components register their styles before head content is flushed. - [#16823](https://redirect.github.com/withastro/astro/pull/16823) [`3df6a45`](https://redirect.github.com/withastro/astro/commit/3df6a453243ff4d1d983d0fb6d259617f50be211) Thanks [@astrobot-houston](https://redirect.github.com/astrobot-houston)! - Fixes missing CSS for conditionally rendered Svelte components in production builds - [#16836](https://redirect.github.com/withastro/astro/pull/16836) [`3d7adfa`](https://redirect.github.com/withastro/astro/commit/3d7adfae7d063661d85d92061a15f728fa5df2bd) Thanks [@LongYC](https://redirect.github.com/LongYC)! - Document compressHTML: "jsx" config is only available since Astro v6.2.0 - [#16864](https://redirect.github.com/withastro/astro/pull/16864) [`334ce13`](https://redirect.github.com/withastro/astro/commit/334ce135807666df283dc4cd4d5f6dad1b1b80cc) Thanks [@cheets](https://redirect.github.com/cheets)! - Fixes a false-positive `Internal Warning: route cache overwritten` logged on every SSR request for dynamic routes </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Enabled. ♻ **Rebasing**: Whenever PR is behind base branch, or you tick the rebase/retry checkbox. 🔕 **Ignore**: Close this PR and you won't be reminded about this update again. --- - [ ] If you want to rebase/retry this PR, check this box --- This PR was generated by [Mend Renovate](https://mend.io/renovate/).
