Description

Craft CMS from 5.8.17 before 5.11.2 contains a privilege escalation vulnerability because getOwners() applies caller criteria without cleansing the query configuration. Authenticated control panel users can invoke attacker-selected static PHP callables via crafted criteria to promote every account to administrator.
