Name of the Vulnerable Software and Affected Versions
Grav versions prior to 3.8.5
Description
The Login plugin contains an issue where the
twofa cancel task accepts a client-controlled redirect field without a nonce. This allows an unauthenticated request to set an external http, https, or protocol-relative Location target. The Controller::execute() function applies the field when taskTwofa cancel() sets no redirect, and Grav::getRedirectResponse() accepts the target through Uri::isExternal(), which can be used to facilitate phishing redirects from a trusted Grav host.Recommendations
Update to version 3.8.5.
