Twig Sandbox Escape by authenticated users with access to editing CMS templates when safemode is enabled.

October is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. In October CMS from version 1.0.319 and before version 1.0.469, an authenticated backend user with the cms.manage_pages, cms.manage_layouts, or cms.manage_partials permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to cms.enableSafeMode being enabled is able to write specific Twig code to escape the Twig sandbox and execute arbitrary PHP. This is not a problem for anyone that trusts their users with those permissions to normally write & manage PHP within the CMS by not having cms.enableSafeMode enabled, but would be a problem for anyone relying on cms.enableSafeMode to ensure that users with those permissions in production do not have access to write & execute arbitrary PHP. Issue has been patched in Build 469 (v1.0.469) and v1.1.0.

October CMS 安全漏洞

October CMS是一套基于PHP和Laravel Web应用程序框架的开源内容管理系统（CMS）。 October 1.0.319和1.0.470之前版本存在安全漏洞，该漏洞源于启用的enableSafeMode能够编写特定的Twig代码来逃避Twig沙箱并执行任意的PHP。
