From 7.12.0 until 7.15.1, certain CSRF checks in React Router v7 Framework Mode were insufficient and run on POST requests, but were bypassed on PUT/PATCH/DELETE requests. This is a low severity vulnerability because modern browser protections (CORS preflight, SameSite cookies) already block the cross-origin attack vectors that this missing CSRF check would otherwise gate. This vulnerability is fixed in 7.15.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","score":3.1},"cwes":["CWE-352"],"references":["https://github.com/remix-run/react-router/security/advisories/GHSA-84g9-w2xq-vcv6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:39:28.638635428+00:00"},"epss":{"cve":"CVE-2026-53663","score":0.00148,"percentile":0.03962,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-84g9-w2xq-vcv6","url":"https://osv.dev/vulnerability/GHSA-84g9-w2xq-vcv6","summary":"React Router: Potential CSRF via PUT/PATCH/DELETE document requests","modified":"2026-09-10T03:51:08.115397519Z","packages":[{"ecosystem":"npm","name":"react-router","purl":"pkg:npm/react-router","ranges":[">=7.12.0 <7.15.1"],"fixed":["7.15.1"]},{"ecosystem":"npm","name":"@remix-run/server-runtime","purl":"pkg:npm/%40remix-run/server-runtime","ranges":[">=2.17.3 <2.17.5"],"fixed":["2.17.5"]}]}],"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).
