Lifecycle Timeline

October is a Content Management System (CMS) and web platform. Prior to 3.7.16 and 4.1.16, fine-grained sub-permission checks for asset and blueprint file operations were not enforced in the CMS and Tailor editor extensions. This only affects backend users who were explicitly granted editor access but had editor.cms_assets or editor.tailor_blueprints specifically withheld, an uncommon permission configuration. In this edge case, such users could perform file operations (create, delete, rename, move, upload) on theme assets or blueprint files despite lacking the required sub-permission. A related operator precedence error in the Tailor navigation also disclosed the theme blueprint directory tree under the same conditions. This vulnerability is fixed in 3.7.16 and 4.1.16.

October CMS versions prior to 3.7.16 and 4.1.16 fail to enforce fine-grained sub-permission checks for asset and blueprint file operations in the CMS and Tailor editor extensions, allowing backend users with editor access but explicitly withheld editor.cms_assets or editor.tailor_blueprints permissions to perform unauthorized file operations (create, delete, rename, move, upload) on theme assets and blueprint files. Additionally, an operator precedence error discloses the theme blueprint directory tree under the same conditions. …
