Open Redirect

Impact

In some situations, it is possible to have open redirects where users can be redirected from your site to any other site using a specially crafted URL.
This is only the case for installations where the default Hostname Identification is used and the environment uses tenants that have force_https set to true (default: false)

Patches

Version 5.7.2 contains the relevant patches to fix this bug. Stripping the URL from special characters to prevent specially crafted URL's from being redirected to.

Workarounds

There is a simple way to work around the security issue

• Set the force_https to every tenant to false
