CVE-2026-53668Network attack vectorHinoki check available

Open redirect and XSS via path misclassification

Published Jul 27, 2026 · Updated Jul 27, 2026

Open redirect and XSS in React Router 6.30.2 through 6.30.4 and 7.9.6 through 7.12.0 allow remote attackers to craft malicious links. The resolvePath function classified colon-bearing pathnames as absolute URLs and skipped double-slash path normalization. A consuming application must place attacker-controlled destinations in an open-redirect flow, and a user must follow the link; exploitation redirects the browser or executes script in the application's origin.
