React Router's same-origin redirect with path starting // causes open redirect via protocol-relative URL reinterpretation

CVE-2026-40181 / GHSA-2j2x-hqr9-3h42

More information

Details

Certain URLs passed to the redirect function can trigger an open redirect to an external domain depending on the level of validation done by the application prior to returning the redirect.

[!NOTE]
This does not impact your React Router application if you are using Declarative Mode (<BrowserRouter>)

Severity

  • CVSS Score: 6.6 / 10 (Medium)
  • Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U

React Router has unexpected external redirect via untrusted paths

CVE-2025-68470 / GHSA-9jcx-v3wj-wh4m

More information

Details

An attacker-supplied path can be crafted so that when a React Router application navigates to it via navigate(), <Link>, or redirect(), the app performs a navigation/redirect to an external URL. This is only an issue if developers pass untrusted content into navigation paths in their application code.

Severity

  • CVSS Score: 6.5 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
