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

Moderate severity GitHub Reviewed Published Jun 5, 2026 in verbb/formie • Updated Jul 17, 2026

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
