Impact This 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. 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. Patches 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. Workarounds Unsupported versions could be patched by adding the following configuration to run in production: ```yaml sylius_channel: debug: false ```
