Description
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a crafted request to the public first-register operation can execute code remotely when local authentication is enabled and no initial user has been created. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
