Formie is a Craft CMS plugin for creating forms. Prior to 2.2.23 and 3.1.31, Formie's formie/integrations/form-settings control panel action in IntegrationsController::actionFormSettings is reachable without the required form integration permissions and passes request-supplied settings to a configured integration. An authenticated attacker can replace outbound host properties such as apiUrl while the server uses stored API keys or OAuth tokens, causing non-blind server-side requests to an attacker-controlled or internal host and returning the remote response. This residual flaw remained because the permission gate added in version 3.1.28 excluded the form-settings action. Sites that permit low-privileged or front-end user authentication can therefore expose integration credentials and internal network responses. This issue is fixed in versions 2.2.23 and 3.1.31.
