"summary": "### Summary\n\nIn affected versions of `astro`, the image optimization endpoint in projects deployed with on-demand rendering allows images from unauthorized third-party domains to be served.\n\n### Details\n\nOn-demand rendered sites built with Astro include an `/_image` endpoint which returns optimized versions of images.\n\nThe `/_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`](https://docs.astro.build/en/reference/configuration-reference/#imagedomains) or [`image.remotePatterns`](https://docs.astro.build/en/reference/configuration-reference/#imageremotepatterns) options).\n\nHowever, a bug in impacted versions of `astro` allows an attacker to bypass the third-party domain restrictions by using a protocol-relative URL as the image source, e.g. `/_image?href=//example.com/image.png`.\n\n### Proof of Concept\n\n1. Create a new minimal Astro project (`astro@5.13.0`).\n\n2. Configure it to use the Node adapter (`@astrojs/node@9.1.0` \u2014 newer versions are not impacted):\n\n ```js\n // astro.config.mjs\n import { defineConfig } from 'astro/config';\n import node from '@astrojs/node';\n\n export default defineConfig({\n \tadapter: node({ mode: 'standalone' }),\n });\n ```\n\n3. Build the site by running `astro build`.\n\n4. Run the server, e.g. with `astro preview`.\n\n5. Append `/_image?href=//placehold.co/600x400` to the preview URL, e.g. <http://localhost:4321/_image?href=//placehold.co/600x400>\n\n6. The site will serve the image from the unauthorized `placehold.co` origin.\n\n### Impact\n\nAllows a non-authorized third-party to create URLs on an impacted site\u2019s origin that serve unauthorized image content.\nIn the case of SVG images, this could include the risk of cross-site scripting (XSS) if a user followed a link to a maliciously crafted SVG.",
