Title

Astro Cloudflare adapter is vulnerable to Server-Side Request Forgery via /_image endpoint

Summary

Astro is a web framework for content-driven websites. Versions 11.0.3 through 12.6.5 are vulnerable to SSRF when using Astro's Cloudflare adapter. When configured with output: 'server' while using the default imageService: 'compile', the generated image optimization endpoint doesn't check the URLs it receives, allowing content from unauthorized third-party domains to be served. a A bug in impacted versions of the @astrojs/cloudflare adapter for deployment on Cloudflare’s infrastructure, allows an attacker to bypass the third-party domain restrictions and serve any content from the vulnerable origin. This issue is fixed in version 12.6.6.

Severity ?

Vulnerability from github – Published: 2025-09-04 19:24 – Updated: 2025-09-05 16:10

Summary

Server-Side Request Forgery via /_image endpoint in Astro Cloudflare adapter

Details

Summary

When using Astro's Cloudflare adapter (@astrojs/cloudflare) configured with output: 'server' while using the default imageService: 'compile', the generated image optimization endpoint doesn't check the URLs it receives, allowing content from unauthorized third-party domains to be served.

Details

On-demand rendered sites built with Astro include an /_image endpoint, which returns optimized versions of images.

The /_image endpoint is restricted to processing local images bundled with the site and also supports remote images from domains the site developer has manually authorized (using the image.domains or image.remotePatterns options).

However, a bug in impacted versions of the @astrojs/cloudflare adapter for deployment on Cloudflare’s infrastructure, allows an attacker to bypass the third-party domain restrictions and serve any content from the vulnerable origin.

PoC

Create a new minimal Astro project (astro@5.13.3)
Configure it to use the Cloudflare adapter (@astrojs/cloudflare@12.6.5) and server output:

```js // astro.config.mjs import { defineConfig } from 'astro/config'; import cloudflare from '@astrojs/cloudflare';

export default defineConfig({ output: 'server', adapter: cloudflare(), }); ```

Deploy to Cloudflare Pages or Workers
Append /_image?href=https://placehold.co/600x400 to the deployment URL.
This will serve the placeholder image from the unauthorised placehold.co domain.

Impact

Allows a non-authorized third-party to create URLs on an impacted site’s origin that serve unauthorized content. This includes the risk of server-side request forgery (SSRF) and by extension cross-site scripting (XSS) if a user follows a link to a maliciously crafted URL.

Severity ?

7.2 (High)
