Collider reports an unconfirmed rumour that the director, who is best known for helming 2011's X-Men: First Class and 2010's Kick-Ass, is a frontrunner for the seventh film.
Vaughn was originally set to direct the upcoming sequel to X-Men: First Class, but dropped out last month and was swiftly replaced by Bryan Singer.
It was announced last week that Disney had bought Lucasfilm, and would release a seventh Star Wars film in 2015.
Harrison Ford is reportedly open to reprising the role of Han Solo in Episode 7.
