How broadly exploitable is this vulnerability?

Exploitability depends on whether your application constructs redirect URLs from untrusted data or uses open redirects that feed into router navigation. If all redirect targets are hard-coded, validated internal routes, the practical risk is significantly reduced even on vulnerable versions.

What level of access does an attacker need?

An attacker typically needs the ability to influence the redirect destination through user-controllable inputs such as query parameters, form fields, or other data that your loaders/actions read. In some cases, control over an upstream open redirect endpoint is enough if its output is used by the router without validation.

What is the safest general fix pattern?

The safest pattern is to constrain all redirect operations to a controlled set of internal routes. Accept only route identifiers or known-safe path fragments, apply strict validation, and resolve them to canonical internal URLs rather than accepting arbitrary URLs from user input.
