## How to fix


Implement server-side validation to reject callback parameters containing http://, https://, //, and backslash sequences; only allow relative in-app paths or use an allow-list of named routes mapped on the server side.

## Technical details

The IController::redirect function in plugins/_userInfo/_userInfo.php fails to properly validate the callback parameter, allowing open redirect to arbitrary absolute URLs. An unauthenticated remote attacker can supply a malicious callback value during login; after successful authentication, the application redirects the user to the attacker's domain. No authentication is required to craft the malicious login request, only user interaction to log in.
