GHSA-cvpc-hccg-wmw4: Formie: Missing authorization in administrative settings allows low-privileged CP users to modify plugin configuration

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.
