Advisories for Npm/@Astrojs/Netlify package

The @astrojs/netlify adapter converts each image.remotePatterns entry into a regular expression that is written to .netlify/v1/config.json under images.remote_images. Netlify's Image CDN uses these regexes as the allowlist that decides which remote image URLs it will optimize. remotePatternToRegex() escapes . in the hostname but interpolates the literal pathname into the regex without escaping regex metacharacters. As a result, the generated allowlist is broader than the pattern the developer declared, and broader …

@astrojs/netlify converts Astro image.remotePatterns into Netlify Image CDN images.remote_images regular expressions with broader semantics than Astro's canonical matcher. A single wildcard hostname such as .example.com is converted to an optional subdomain regex, so the apex host matches. A single wildcard pathname such as /ok/ is converted without end anchoring, so deeper paths match by prefix.
