The manipulation as part of a Content-Type leads to a improper interaction between multiple correctly-behaving entities vulnerability. CWE is classifying the issue as CWE-435.

This is going to have an impact on availability. The summary by CVE is:

In Symfony before version 4.4, 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.
