Fixes https://github.com/TreyWW/MyFinances/security/code-scanning/20
To fix the problem, we need to validate the
redirect_url
to ensure it is safe to use. We can use Django'surl_has_allowed_host_and_scheme
function 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_scheme
function fromdjango.utils.http
.redirect_url
before performing the redirect.redirect_url
is not valid, redirect to a default safe page, such as the dashboard.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
