The 20-year-old has been on loan at Championship side Leicester City this past season where he notched up 12 goals during the loan spell.
Despite competition for places with the Black Cats, Waghorn now wants to concentrate on playing regular football at his parent club.
"I couldn't tell you about my future," he told the Leicester Mercury.
"I have been asked about it ever since I scored my very first goal. I don't know what is going to happen.
"I am going to go back to Sunderland for pre-season and work hard, and then see what happens and see what offers come in. I am going to play it by ear and work hard wherever I go.
Sunderland boss Steve Bruce has made public his expectations for the youngster and Waghorn is hoping he can impress.
Waghorn added: "It has been great to know that your parent club's manager is looking out for you and to hear he has such high hopes for me is fantastic.
"I am not saying I won't come on loan again, but I want to settle down somewhere and get a regular spot.
"If it means going out on loan again, I would be a little bit disappointed. But, if I get a permanent move or stay at Sunderland, I just want to stay at one place and get my head down, and push on from there."
Waghorn missed a penalty in Leicester City’s Championship play-off semi final against Cardiff City but the England Under-19 international will be looking to bounce back at Sunderland next season.
