{"cve":"CVE-2026-102983","nvd":{"published":"2026-09-30T15:22:22.800","modified":"2026-09-30T19:38:27.293","status":"Awaiting Analysis","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":null,"cwes":["CWE-625","CWE-918"],"references":["https://github.com/withastro/astro/commit/e362d4cf540b27730482455c8fc02efe57d16702","https://github.com/withastro/astro/pull/17752","https://github.com/withastro/astro/releases/tag/@astrojs/netlify@8.2.4","https://github.com/withastro/astro/security/advisories/GHSA-4233-jc72-56c5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-102983","score":0.0031,"percentile":0.23678,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4233-jc72-56c5","url":"https://osv.dev/vulnerability/GHSA-4233-jc72-56c5","summary":"Astro: Netlify Image CDN allowlist bypass enables SSRF","modified":"2026-09-30T23:45:04.012782965Z","packages":[{"ecosystem":"npm","name":"@astrojs/netlify","purl":"pkg:npm/%40astrojs/netlify","ranges":[">=5.2.0 <8.2.4"],"fixed":["8.2.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
