CWE-601  (opens in a new tab)

How to fix?

Upgrade Firefox to version 114 or higher.

Overview

Affected versions of this package are vulnerable to Open Redirect. When choosing a site-isolated process for a document loaded from a data URL that resulted from a redirect, Firefox would load that document in the same process as the site that issued the redirect. This bypassed the site-isolation protections against Spectre-like attacks on sites that host an "open redirect".
