Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

Craft CMS from 5.0.0 before 5.10.14 contains a missing authorization vulnerability in AppController::actionSwitchToLicensedEdition() that lets any authenticated user change the installed edition. Low-privileged front-end users can call the action route when the licensed edition mismatches to persistently downgrade the site edition in project config, which admins cannot reverse from the control panel.
