Prior to 13.1.10, the fetch() call for remote images in packages/integrations/cloudflare/src/utils/image-binding-transform.ts uses the default redirect: 'follow' behavior. This allows the Cloudflare Worker to follow HTTP redirects to arbitrary URLs, bypassing the isRemoteAllowed() domain allowlist check which only validates the initial URL. This vulnerabiity is caused by an incomplete fix for CVE-2025-58179. This vulnerability is fixed in 13.1.10.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L","score":2.2},"cwes":["CWE-918"],"references":["https://github.com/withastro/astro/security/advisories/GHSA-88gm-j2wx-58h6","https://github.com/withastro/astro/security/advisories/GHSA-88gm-j2wx-58h6"],"products":[],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-41321","score":0.00199,"percentile":0.09615,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-88gm-j2wx-58h6","url":"https://osv.dev/vulnerability/GHSA-88gm-j2wx-58h6","summary":"Cloudflare has SSRF via redirect following through its image-binding-transform endpoint (incomplete fix for GHSA-qpr4)","modified":"2026-05-05T16:05:51.817634Z","packages":[{"ecosystem":"npm","name":"@astrojs/cloudflare","purl":"pkg:npm/%40astrojs/cloudflare","ranges":["<13.1.10"],"fixed":["13.1.10"]}]}],"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).
