{"apiVersion":"1.0","identifier":"CVE-2026-73425","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.","publishedAt":"2026-08-12T21:17:41","lastModifiedAt":"2026-08-13T13:19:17","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73425","cvssScore":3.7,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","epssProbability":0.00171,"riskScore":0.38,"affectedProduct":"Astro","affectedVersions":"<8.1.2","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73425","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73425","en":"https://www.redsauce.net/en/cves/CVE-2026-73425","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73425","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73425","de":"https://www.redsauce.net/de/cves/CVE-2026-73425","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73425","el":"https://www.redsauce.net/el/cves/CVE-2026-73425"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73425"}}
