body: <p>I'm running a Rails on Heroku over a year but today i'm facing a issue which not push fails to Heroku latest commit, when I run <code>git push heroku master</code> then like below</p>
  
  <pre><code>remote:  !     A security vulnerability has been detected in your application.

  remote:  !     To protect your application you must either upgrade to Sprockets version "3.7.2"
  remote:  !     or disable dynamic compilation at runtime by setting:

  remote:  !     ```
  remote:  !     config.assets.compile = true # Disables security vulnerability
  remote:  !     ```
  remote:  !
