SCA: security update for symfony/http-foundation, symfony/symfony (GHSA-mcx4-f5f5-4859)

medium Tenable Self-Hosted Container Security Plugin ID 423367

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In Symfony before versions 4.4.7 and 5.0.7, when a `Response` does not contain a `Content-Type` header,
 affected versions of Symfony can fallback 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 prevent the use of the website by other users. This has been patched in
 versions 4.4.7 and 5.0.7. (CVE-2020-5255)
