CVE-2026-1487
At a glance
CVE-2026-1487 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Appointment Booking Plugin WordPress plugin, affecting versions <= 5.2.7. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 5.2.8; sites on affected versions should update now. Disclosed March 2026, reported by Chiao-Lin Yu (Steven Meow).
Vulnerability Overview
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to SQL Injection via the JSON Import in all versions up to, and including, 5.2.7 due to insufficient validation on the user-supplied JSON data. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary SQL queries on the database that can be used to extract information via time-based techniques, drop tables, or modify data.
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, integrity.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Appointment Booking Plugin <= 5.2.7 takes an account at Administrator 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 Appointment Booking Plugin the fix is 5.2.8: builds <= 5.2.7 are affected, anything from 5.2.8 onward is not.
Remediation
Update to version 5.2.8, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator 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: Appointment Booking Plugin 5.2.8 closes this, and updating the plugin is the step that ends it.
