Problem

Possible unprotected redirect

Location

app/controllers/list_controller.rb:270

redirect_to(Category.find_by_id(params[:id].to_i).url, :status => 301)

Category description: Sometimes redirect_to can be used with a user-supplied value that may allow the attacker to change the :host option and load a malicious script from a third party website.

Solution: fix the issue in app/controllers/list_controller.rb or mark it as false positive.
