A vulnerability was found in Sylius up to 1.3.16/1.4.12/1.5.9/1.6.5. It has been declared as critical. This vulnerability affects some unknown processing of the component Channel Handler. The manipulation of the argument _channel_code as part of a GET Parameter leads to a request smuggling vulnerability. The CWE definition for the vulnerability is CWE-444. The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Affected versions of Sylius give attackers the ability to switch channels via the _channel_code GET parameter in production environments. This was meant to be enabled only when kernel.debug is set to true. However, if no sylius_channel.debug is set explicitly in the configuration, the default value which is kernel.debug will be not resolved and cast to boolean, enabling this debug feature even if that parameter is set to false. Patch has been provided for Sylius 1.3.x and newer - 1.3.16, 1.4.12, 1.5.9, 1.6.5. Versions older than 1.3 are not covered by our security support anymore.

The weakness was published 01/27/2020 (GitHub Repository). The advisory is available at github.com. This vulnerability was named CVE-2020-5218 since 01/02/2020. The exploitation appears to be difficult. The attack can be initiated remotely. Required for exploitation is a single authentication. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit.
