Description

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:

sylius_channel:
    debug: false
