Upgrade sylius/sylius to 1.3.16Upgrade sylius/sylius to 1.4.12Upgrade sylius/sylius to 1.5.9Upgrade sylius/sylius to 1.6.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for sylius/syliusHow to Check if You Are Affected
To determine whether your application is affected by CVE-2020-5218, inspect your project dependencies for Sylius/sylius:
inspect dependencies for sylius/syliusAnalyze the terminal output to locate any version of Sylius/sylius in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.16), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'), where 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. In Sylius/sylius, software state validation or input boundaries are circumvented during processing.

"details" : "### Impact\n\nThis vulnerability gives 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. \n\nHowever, 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.\n\n### Patches\n\nPatch 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.\n\n### Workarounds\n\nUnsupported versions could be patched by adding the following configuration to run in production:\n\n```yaml\nsylius_channel:\n debug: false\n```",
