Summary
by MITRE • 08/01/2026

The vulnerability resides within the Booking for Appointments and Events Calendar WordPress plugin, specifically affecting versions prior to 2.4.4 where inadequate input validation and access control mechanisms exist during customer import operations. This flaw represents a critical authorization bypass issue that allows malicious actors with the Amelia Manager role to manipulate user data beyond their intended scope, creating potential pathways for data corruption and unauthorized modifications.
The technical implementation of this vulnerability stems from insufficient sanitization and validation of import parameters within the plugin's customer management functionality. When users with the Amelia Manager role submit import requests, the system fails to properly validate which database columns can be modified through the import process, allowing attackers to specify arbitrary field names that correspond to sensitive user data columns such as passwords, roles, or other administrative attributes. This type of vulnerability aligns with CWE-20, known as Improper Input Validation, and specifically manifests as an unauthorized modification of user records through insecure data handling practices.
The operational impact of this vulnerability extends beyond simple data manipulation to potentially enable privilege escalation attacks within the WordPress environment. An attacker with the Amelia Manager role could leverage this weakness to modify user accounts, escalate privileges, or corrupt critical system data, potentially compromising the entire booking system and associated user information. The attack vector requires minimal privileges but can result in significant damage to both user privacy and system integrity.
Mitigation strategies should focus on implementing proper access control restrictions during import operations, ensuring that only authorized fields can be modified through customer import functionality. Plugin updates to version 2.4.4 or later are essential, as they contain the necessary fixes for input validation and authorization checks. Additionally, administrators should implement role-based access controls to limit the permissions granted to Amelia Manager users, following principle of least privilege practices. Regular security audits of WordPress plugins and monitoring of import operations can help detect unauthorized modifications. This vulnerability also aligns with ATT&CK technique T1078.004, which covers Valid Accounts - Cloud Infrastructure, as it exploits legitimate user roles to perform unauthorized actions within the system.
