Server-Side Request Forgery (SSRF)

Astro is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to improperly anchored regular expressions used to validate Netlify Image CDN remote-image URLs, which allows an unauthenticated attacker to bypass host allowlists and cause the Image CDN to request...

Astro: Netlify Image CDN allowlist bypass enables SSRF

Summary The @astrojs/netlify adapter generated regular expressions for Netlify Image CDN remote-image allowlists without anchoring them to the beginning of the URL. Netlify evaluates these expressions with RegExp.test, so an allowed image origin appearing anywhere in a URL, including its path or...

CVE-2026-73425

CVE-2026-73425 affects Astro with the Netlify adapter prior to 8.1.2. The root cause is in remotePatternToRegex: dots in hostnames are escaped, but pathname metacharacters (., +, ?, (, [) are not escaped, so a restrictive pathname like /img/v1.0/file can match unintended paths. Netlify enforces t...
