Reporting Bug (forward the link of the signature request)

Hi,

While testing the uniqueness of the signature to the signature request sent from the application, we tried a scenario and encountered the following situation:
Scenario description:
Step 1: Sender sends out the signature request to User 1. 
Step 2. User 1 receives the link to the document to be signed
Step 3. User 1 copies the link (not forwarding the email) and forwards it to User 2, who is obviously not the same as User 1.
Step 4. User 2 opens the link and, ignoring the fact that he is not the one being asked to sign, opens the document and clicks on the signature field. The system then automatically places the image of User 1's signature and the email field contains User 1's email address.
Note: User 1 and User 2 do not have shared their login credentials or signature image.

I am waiting for Adobe's respone about it!
