CVE-2026-102983 · Astro: Netlify Image CDN allowlist bypass enables SSRF

Здесь приведены факты из открытых источников об уязвимостях. Перед обновлением ознакомьтесь с исходным сообщением.

Astro is a web framework for content-driven websites. From 5.2.0 until 8.2.4, the @astrojs/netlify adapter generates regular expressions for Netlify Image CDN remote-image allowlists without anchoring them to the beginning of the URL. Because Netlify evaluates these expressions with RegExp.test(), an allowed origin appearing only in a source URL's path or query can satisfy image.domains or image.remotePatterns while the URL's actual host remains attacker-controlled. An unauthenticated request to the public /.netlify/images endpoint can therefore cause the Image CDN to request attacker-selected URLs and may probe or reach internal services. Netlify egress protections may constrain reachable targets, and image transformation limits direct response exfiltration; no confidentiality or integrity impact has been demonstrated. This issue is fixed in version 8.2.4.
