🚨 Security Vulnerability: CVE-2026-22029

Severity: HIGH
CVSS Score: N/A

Description

React Router vulnerable to XSS via Open Redirects

React Router is a router for React. In @remix-run/router version prior to 1.23.2. and react-router 7.0.0 through 7.11.0, React Router (and Remix v1/v2) SPA open navigation redirects originating from loaders or actions in Framework Mode, Data Mode, or the unstable RSC modes can result in unsafe URLs causing unintended javascript execution on the client. This is only an issue if you are creating redirect paths from untrusted content or via an open redirect. There is no impact if Declarative Mode () is being used. This issue has been patched in @remix-run/router version 1.23.2 and react-router version 7.12.0.

@clubanderson I’d like to take this up. My understanding is that the fix involves upgrading @remix-run/router from 1.23.0 to 1.23.2 to address CVE-2026-22029. Are any additional code changes expected beyond this, aside from reviewing redirects constructed from untrusted input? Please let me know if this aligns with your expectations.
