At a glance
CVE-2024-13746 is a medium-severity Missing Authorization vulnerability in the Booking Calendar and Notification WordPress plugin, affecting versions <= 4.0.3. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed February 2025, reported by Pham Van Tam.
Vulnerability Overview
The Booking Calendar and Notification plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to missing capability checks on the wpcb_all_bookings(), wpcb_update_booking_post(), and wpcb_delete_posts() functions in all versions up to, and including, 4.0.3. This makes it possible for unauthenticated attackers to extract data, create or update bookings, or delete arbitrary posts.
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 privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Booking Calendar and Notification <= 4.0.3 carries this weakness at wpcb_all_bookings(), and reaching it takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. No fixed build of this plugin is recorded for Booking Calendar and Notification yet, so installs running <= 4.0.3 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
