title: SensioLabs Security Check Error Symfony 5
body: <p>I installed the SensioLabs security checker recipe using composer and it looks like it installed the recipe but I get the following two warnings</p>
  
  <h2>symfony/http-foundation (v5.0.5)</h2>
  
  <ul>
  <li>[CVE-2020-5255][]: Prevent cache poisoning via a Response Content-Type header</li>
  </ul>
  
  <h2>symfony/security-http (v5.0.5)</h2>
  
  <ul>
  <li>[CVE-2020-5275][]: All rules set in "access_control" are required when the firewall is configured with the unanimous strategy</li>
  </ul>
  
  <p>I would like to know what I should do to fix this please? I am using the latest version of Symfony 5 on a Linux Mint 19 machine.</p>
