CVE-2020-5255
March 30, 2020
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.
