The Event Booking Manager for WooCommerce WordPress plugin before 5.3.7 does not properly verify authorization on the object being modified when quick-editing events, only checking a global capability, allowing users with the Contributor role and above to modify the title and publication status of arbitrary posts and pages on the site, including content they do not own.
