CVE-2025-12042

Course Booking System <= 6.1.5 - Missing Authorization to Unauthenticated Booking Data Export

Published Nov 8, 2025 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

The Course Booking System plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check in the csv-export.php file in all versions up to, and including, 6.1.5. This makes it possible for unauthenticated attackers to directly access the file and obtain an export of all booking data.

Analysis

Technical impact

The Course Booking System plugin for WordPress contains an authorization flaw that allows any visitor to download booking data without “edit_posts” or other capability checks. By requesting the csv-export.php endpoint, an unauthenticated user can receive a full CSV export of all stored bookings, exposing user information, dates, and contact details. The weakness is a missing capability check, identified as CWE‑862 and providing a direct path to sensitive data exposure.

Affected Systems

WordPress sites that use the Course Booking System plugin, version 6.1.5 or earlier. The issue exists in all releases up to and including 6.1.5.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate confidentiality impact with no authentication required. The EPSS score below 1% suggests a low probability of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. Attackers can trigger the flaw simply by accessing the CSV export URL from any network that can reach the affected site, meaning the attack vector is network-based and does not require privileged credentials. Once the request is made, the exported data is returned without further checks.

Affected Products
