Description

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.

Affected configurations

• sensiolabs symfony (>= 4.4.0 < 4.4.7) • sensiolabs symfony (>= 5.0.0 < 5.0.7)
