DescriptionCVE.org

The LatePoint - Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to privilege escalation via password reset in all versions up to, and including, 5.2.7. This is due to the plugin allowing users with a LatePoint Agent role, who are creating new customers to set the 'wordpress_user_id' field. This makes it possible for authenticated attackers, with Agent-level access and above, to gain elevated privileges by linking a customer to the arbitrary user ID, including administrators, and then resetting the password.

Executive ViewAI

Why It Matters

A privilege escalation vulnerability in the LatePoint WordPress booking plugin affects any organization using this plugin with Agent-level users or higher. Attackers with legitimate Agent credentials can exploit password reset functionality to gain unauthorized administrative access to WordPress, potentially compromising customer data, website integrity, and business operations.

Business Impact: High

Compensating Controls

Immediately revoke Agent-level privileges for all non-essential users; disable customer creation functionality if not critical to operations; implement Web Application Firewall (WAF) rules to monitor and block suspicious password reset requests; restrict database access to the 'wordpress_user_id' field via database-level permissions; enable comprehensive audit logging for all user creation and privilege escalation events; consider network segmentation to limit Agent account access scope; monitor for suspicious user account linkages and privilege elevation attempts.
