    Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the X-React-Router-Prerender-Data header.

    Note:

    This is only exploitable if the application is running in Framework mode, which is the default configuration, it has a caching system in place and the target page utilizes a loader.

    How to fix Insufficient Verification of Data Authenticity?

    Upgrade @react-router/dev to version 7.5.2 or higher.
