AI Analysis
Technical Summary
The Booking for Appointments and Events Calendar WordPress plugin versions before 9.7 contain an authorization bypass vulnerability (CWE-639). Authenticated employees with Employee Panel login can access and modify personal data of any customer without proper verification of their relationship to the customer. This is possible by enumerating sequential customer record identifiers, allowing unauthorized data access and modification.
Potential Impact
An authenticated employee can read and modify personal data of any customer in the system, potentially leading to unauthorized disclosure and alteration of sensitive customer information. The impact is limited to confidentiality and integrity of customer data, with no availability impact. The CVSS score is 3.8 (low severity).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch is indicated, users should monitor vendor communications for updates. Until a fix is available, restrict Employee Panel access to trusted personnel only and consider additional access controls to limit exposure.
