Details
As written in the advisory (Markdown source, shown as plain text).
### 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`
