At a glance
CVE-2026-13454 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the MotoPress Appointment Booking WordPress plugin, affecting versions <= 2.4.5. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Staff level or above. The issue is fixed in version 2.4.6; sites on affected versions should update now. Disclosed June 2026, reported by MatilJ.
Vulnerability Overview
The MotoPress Appointment Booking plugin for WordPress is vulnerable to generic SQL Injection via the 's' parameter in all versions up to, and including, 2.4.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the mpa_appointment_employee custom role, meaning any user assigned this role can perform the attack.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in MotoPress Appointment Booking <= 2.4.5 takes an account at Staff level or above. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For MotoPress Appointment Booking the fix is 2.4.6: builds <= 2.4.5 are affected, anything from 2.4.6 onward is not.
Remediation
Update to version 2.4.6, or a newer patched version
How does WordSec protect against this?
An attacker needs Staff access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: MotoPress Appointment Booking 2.4.6 closes this, and updating the plugin is the step that ends it.
