Administrators should avoid opening or updating customer records received from untrusted sources until a fix is available. Monitor vendor advisories for updates. Consider restricting access to the REST endpoint or disabling the plugin if feasible until remediation is provided.
Description
The Rox Appointment Booking plugin for WordPress up to version 1.3.1 contains a privilege escalation vulnerability via mass assignment. An unauthenticated attacker can inject an arbitrary WordPress user ID into a customer record through a public REST endpoint. If an administrator later opens and updates this poisoned record, the attacker's supplied user ID and email are used to update the administrator's account, enabling full account takeover via password reset. Exploitation requires the attacker to know or guess a valid administrator user ID and for an administrator to interact with the malicious record.
