CyberRota Analysis
AI-GeneratedThe Astro web framework's Netlify adapter prior to version 8.1.2 is vulnerable due to improper handling of regular expression metacharacters in image pathname values, which could allow unauthorized image optimization on paths that should be restricted. This could lead to unintended exposure or manipulation of images, impacting the integrity of content-driven websites. Developers and organizations using Astro with Netlify should prioritize upgrading to version 8.1.2 to mitigate this risk.

Original NVD Description
Astro is a web framework for content-driven websites. Prior to 8.1.2, the Astro Netlify adapter converts each image.remotePatterns entry into a regular expression written to .netlify/v1/config.json under images.remote_images for Netlify's Image CDN allowlist. In packages/integrations/netlify/src/index.ts, remotePatternToRegex() escapes dots in hostname values but interpolates literal pathname values without escaping regular expression metacharacters such as ., +, ?, (, and [, so a restrictive pathname such as /img/v1.0/file also matches metacharacter-adjacent paths, including paths that cross a segment. Netlify enforces the generated regular expression directly and Astro's matchPattern() helper does not revalidate the request, allowing optimization of images on an already-allowed host that the declared pathname was intended to exclude. This issue is fixed in version 8.1.2.
