CVE-2020-5220

Sylius ResourceBundle accepts and uses any serialisation groups to be passed via a HTTP header.

Anyone exposing an API with ResourceBundle's controller is affected. The vulnerable versions are: <1.3 || >=1.3.0 <=1.3.12 || >=1.4.0 <=1.4.5 || >=1.5.0 <=1.5.0 || >=1.6.0 <=1.6.2. The patch is provided for Sylius ResourceBundle 1.3.13, 1.4.6, 1.5.1 and 1.6.3, but not for any versions below 1.3.
