Fixes https://github.com/TreyWW/MyFinances/security/code-scanning/20
To fix the problem, we need to validate the
redirect_urlto ensure it is safe to use. We can use Django'surl_has_allowed_host_and_schemefunction to check that the URL is safe to redirect to. This function ensures that the URL does not contain an explicit host name unless it is in the list of allowed hosts.url_has_allowed_host_and_schemefunction fromdjango.utils.http.redirect_urlbefore performing the redirect.redirect_urlis not valid, redirect to a default safe page, such as the dashboard.Suggested fixes powered by Copilot Autofix.
