When processing Deeplink scheme, Happypoint mobile app 6.3.19 and earlier versions doesn't check Deeplink URL correctly.

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
