CVE-2026-107369 · Improper Validation of Post-Login Redirect URL in nextjs-auth0
This page contains facts from public vulnerability sources. Check the original advisory before updating.
The auth0/nextjs-auth0 SDK validates that the returnTo parameter is a same-origin URL. The SDK then stores this value and, in a later step, reconstructs it for the post-authentication redirect. The reconstruction logic can produce a URL that browsers interpret as an absolute or scheme-relative path, leading to a redirect to an unintended domain.
