DescriptionCVE.org

The Booking for Appointments and Events Calendar WordPress plugin before 2.4.10 does not verify that the user editing a customer or employee record is entitled to modify the WordPress account linked to it, allowing users holding Amelia's customer or employee management permissions to set the password and email address of other users' WordPress accounts and take them over.

AnalysisAI

Privilege escalation via IDOR in the Amelia 'Booking for Appointments and Events Calendar' WordPress plugin before 2.4.10 allows users holding plugin-level customer or employee management permissions to overwrite the email address and password of any linked WordPress account, achieving full account takeover of other users including administrators. The flaw stems from missing entitlement verification when editing customer or employee records: the plugin confirms the actor holds management rights within Amelia but never confirms ownership of the underlying WordPress account being modified. …
