Summary: October CMS safe mode bypass using Twig sandbox escape
Details: ### Impact An authenticated backend user with the `editor.cms_pages`, `editor.cms_layouts`, or `editor.cms_partials` permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to `cms.safe_mode` being enabled can write specific Twig code to escape the Twig sandbox and execute arbitrary PHP. This is not a problem for anyone who trusts their users with those permissions to usually write and manage PHP within the CMS by not having `cms.safe_mode` enabled. Still, it would be a problem for anyone relying on `cms.safe_mode` to ensure that users with those permissions in production do not have access to write and execute arbitrary PHP. ### Patches This issue has been patched in v3.4.15. ### Workarounds As a workaround, remove the specified permissions from untrusted users. ### References Credits to: - [Vasiliy Bodrov](https://github.com/whatev3n) ### For more information If you have any questions or comments about this advisory: * Email us at [[email protected]](mailto:[email protected])
