CVE-2020-5255 (GCVE-0-2020-5255)

Vulnerability from cvelistv5 – Published: 2020-03-30 19:30 – Updated: 2024-08-04 08:22
VLAI?
Summary
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.
Severity ?
