Detailsinfo

A vulnerability, which was classified as problematic, has been found in CMS up to 3.7.15/4.1.15. Affected by this issue is an unknown part of the component Configuration Handler. The manipulation with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-29179 since 03/04/2026. The exploitation is known to be difficult. The attack may be launched remotely. Additional levels of successful authentication are necessary for exploitation. There are neither technical details nor an exploit publicly available.

Upgrading to version 3.7.16 or 4.1.16 eliminates this vulnerability.
