{"id":"GHSA-prg5-hg25-8grq","aliases":["CVE-2020-5218","CVE-2020-5220","GHSA-8vp7-j5cj-vvm2"],"title":"Ability to switch channels via GET parameter enabled in production environments","description":"### 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```","severity":"medium","score":4.4,"published":"2020-01-31T18:00:43.000Z","modified":"2026-07-08T06:49:46.850Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"0"},{"fixed":"1.3.16"}],"type":"ECOSYSTEM"}],"versions":["v0.1.0","v0.10.0","v0.11.0","v0.12.0","v0.13.0","v0.14.0","v0.15.0","v0.16.0","v0.17.0","v0.18.0","v0.19.0","v0.2.0","v0.3.0","v0.5.0","v0.6.0","v0.7.0","v0.8.0","v0.9.0","v1.0.0","v1.0.0-alpha.1","v1.0.0-alpha.2","v1.0.0-beta.1","v1.0.0-beta.2","v1.0.0-beta.3","v1.0.0-rc.1","v1.0.0-rc.2","v1.0.1","v1.0.10","v1.0.11","v1.0.12","v1.0.13","v1.0.14","v1.0.15","v1.0.16","v1.0.17","v1.0.18","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v1.0.9","v1.1.0","v1.1.0-RC","v1.1.1","v1.1.10","v1.1.11","v1.1.12","v1.1.13","v1.1.14","v1.1.15","v1.1.16","v1.1.17","v1.1.18","v1.1.2","v1.1.3","v1.1.4","v1.1.5","v1.1.6","v1.1.7","v1.1.8","v1.1.9","v1.2.0","v1.2.0-BETA","v1.2.0-RC","v1.2.1","v1.2.10","v1.2.11","v1.2.12","v1.2.13","v1.2.14","v1.2.15","v1.2.16","v1.2.17","v1.2.2","v1.2.3","v1.2.4","v1.2.5","v1.2.6","v1.2.7","v1.2.8","v1.2.9","v1.3.0","v1.3.0-BETA","v1.3.1","v1.3.10","v1.3.11","v1.3.12","v1.3.13","v1.3.14","v1.3.15","v1.3.2","v1.3.3","v1.3.4","v1.3.5","v1.3.6","v1.3.7","v1.3.8","v1.3.9"],"fixed":["1.3.16"]},{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"1.4.0"},{"fixed":"1.4.12"}],"type":"ECOSYSTEM"}],"versions":["v1.4.0","v1.4.1","v1.4.10","v1.4.11","v1.4.2","v1.4.3","v1.4.4","v1.4.5","v1.4.6","v1.4.7","v1.4.8","v1.4.9"],"fixed":["1.4.12"]},{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"1.5"},{"fixed":"1.5.9"}],"type":"ECOSYSTEM"}],"versions":["v1.5.0","v1.5.0-RC.1","v1.5.1","v1.5.2","v1.5.3","v1.5.4","v1.5.5","v1.5.6","v1.5.7","v1.5.8"],"fixed":["1.5.9"]},{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"1.6.0"},{"fixed":"1.6.5"}],"type":"ECOSYSTEM"}],"versions":["v1.6.0","v1.6.1","v1.6.2","v1.6.3","v1.6.4"],"fixed":["1.6.5"]},{"ecosystem":"Packagist","name":"sylius/resource-bundle","ranges":[{"events":[{"introduced":"1.4.0"},{"fixed":"1.4.6"}],"type":"ECOSYSTEM"}],"versions":["v1.4.0","v1.4.1","v1.4.2","v1.4.3","v1.4.4","v1.4.5"],"fixed":["1.4.6"]},{"ecosystem":"Packagist","name":"sylius/resource-bundle","ranges":[{"events":[{"introduced":"1.5.0"},{"fixed":"1.5.1"}],"type":"ECOSYSTEM"}],"versions":["v1.5.0"],"fixed":["1.5.1"]},{"ecosystem":"Packagist","name":"sylius/resource-bundle","ranges":[{"events":[{"introduced":"1.6.0"},{"fixed":"1.6.3"}],"type":"ECOSYSTEM"}],"versions":["v1.6.0","v1.6.1","v1.6.2"],"fixed":["1.6.3"]},{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"0"},{"fixed":"1.3.12"}],"type":"ECOSYSTEM"}],"versions":["v0.1.0","v0.10.0","v0.11.0","v0.12.0","v0.13.0","v0.14.0","v0.15.0","v0.16.0","v0.17.0","v0.18.0","v0.19.0","v0.2.0","v0.3.0","v0.5.0","v0.6.0","v0.7.0","v0.8.0","v0.9.0","v1.0.0","v1.0.0-alpha.1","v1.0.0-alpha.2","v1.0.0-beta.1","v1.0.0-beta.2","v1.0.0-beta.3","v1.0.0-rc.1","v1.0.0-rc.2","v1.0.1","v1.0.10","v1.0.11","v1.0.12","v1.0.13","v1.0.14","v1.0.15","v1.0.16","v1.0.17","v1.0.18","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v1.0.9","v1.1.0","v1.1.0-RC","v1.1.1","v1.1.10","v1.1.11","v1.1.12","v1.1.13","v1.1.14","v1.1.15","v1.1.16","v1.1.17","v1.1.18","v1.1.2","v1.1.3","v1.1.4","v1.1.5","v1.1.6","v1.1.7","v1.1.8","v1.1.9","v1.2.0","v1.2.0-BETA","v1.2.0-RC","v1.2.1","v1.2.10","v1.2.11","v1.2.12","v1.2.13","v1.2.14","v1.2.15","v1.2.16","v1.2.17","v1.2.2","v1.2.3","v1.2.4","v1.2.5","v1.2.6","v1.2.7","v1.2.8","v1.2.9","v1.3.0","v1.3.0-BETA","v1.3.1","v1.3.10","v1.3.11","v1.3.2","v1.3.3","v1.3.4","v1.3.5","v1.3.6","v1.3.7","v1.3.8","v1.3.9"],"fixed":["1.3.12"]},{"ecosystem":"Packagist","name":"sylius/sylius","ranges":[{"events":[{"introduced":"1.4.0"},{"fixed":"1.4.4"}],"type":"ECOSYSTEM"}],"versions":["v1.4.0","v1.4.1","v1.4.2","v1.4.3"],"fixed":["1.4.4"]},{"ecosystem":"Packagist","name":"sylius/resource-bundle","ranges":[{"events":[{"introduced":"1.0.0"},{"fixed":"1.3.13"}],"type":"ECOSYSTEM"}],"versions":["v1.0.0","v1.0.1","v1.0.10","v1.0.11","v1.0.12","v1.0.13","v1.0.14","v1.0.15","v1.0.16","v1.0.17","v1.0.18","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v1.0.9","v1.1.0","v1.1.0-RC","v1.1.1","v1.1.10","v1.1.11","v1.1.12","v1.1.13","v1.1.14","v1.1.15","v1.1.17","v1.1.18","v1.1.2","v1.1.3","v1.1.4","v1.1.5","v1.1.6","v1.1.7","v1.1.8","v1.1.9","v1.2.0","v1.2.0-BETA","v1.2.0-RC","v1.2.1","v1.2.10","v1.2.11","v1.2.12","v1.2.13","v1.2.14","v1.2.15","v1.2.16","v1.2.17","v1.2.2","v1.2.3","v1.2.4","v1.2.5","v1.2.6","v1.2.7","v1.2.8","v1.2.9","v1.3.0","v1.3.0-BETA","v1.3.1","v1.3.10","v1.3.11","v1.3.12","v1.3.2","v1.3.3","v1.3.4","v1.3.5","v1.3.6","v1.3.7","v1.3.8","v1.3.9"],"fixed":["1.3.13"]}],"references":["https://github.com/Sylius/Sylius/security/advisories/GHSA-prg5-hg25-8grq","https
