info:
  name: Astro Cloudflare Adapter - Server Side Request Forgery
  author: HoangAnhThai
  severity: high
  description: |
    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.
  impact: |
    Unauthenticated attackers can bypass third-party domain restrictions to serve arbitrary content from unauthorized domains through the image optimization endpoint, potentially enabling XSS attacks.
  remediation: |
    Upgrade Astro's @astrojs/cloudflare adapter to version 12.6.6 or later that properly validates image URLs.
