Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Formie, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Formie contains a missing authorization vulnerability in administrative settings routes. An authenticated, non-admin Craft CMS control panel user with limited Formie access could directly access Formie settings pages and modify global plugin configuration. In affected versions, Formie settings-related control panel routes did not consistently enforce the required settings permission on the server side. A low-privileged Craft CMS control panel user with limited Formie access could access /admin/formie/settings, save changes to global plugin settings, and access /admin/formie/settings/import-export. The issue has been fixed by enforcing the formie-accessSettings permission across Formie settings controllers and related settings actions. ### Impact An authenticated low-privileged CP user may be able to: - Access Formie administrative settings. - Modify global Formie plugin configuration. - Access Formie import/export settings functionality. This may allow configuration tampering and disruption of form-related workflows. Exploitation requires an authenticated Craft CMS control panel account.
