Improper Input Validation

CVE-2020-5255

Severity Medium
Score 4.3/10

Summary

In Symfony before 4.4.7 and 5.0.x before 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.
