  script_tag(name:"insight", value:"The following vulnerabilities exist:

  - When a Response does not contain a Content-Type header, Symfony falls back to the format defined
  in the Accept header of the request, leading to a possible mismatch between the response's content
  and Content-Type header. When the response is cached, this can lead to a corrupted cache where the
  cached format is not the right one (CVE-2020-5255)

  - When a Firewall checks an access control rule (using the unanimous strategy), it iterates over
  all rule attributes and grant access only if all calls to the accessDecisionManager decide to grant access.

  A bug was introduced that prevents the check of attributes as soon as
  accessDecisionManager decide to grant access on one attribute (CVE-2020-5275)");
