Vulnerability Overview
The Five Star Restaurant Reservations – WordPress Booking Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to 2.7.23. This makes it possible for authenticated attackers, with custom role-level access and above, to perform an unauthorized action.
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.
CWE-862: Missing Authorization
Reaching this weakness in Five Star Restaurant Reservations < 2.7.23 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. For Five Star Restaurant Reservations the fix is 2.7.23: builds < 2.7.23 are affected, anything from 2.7.23 onward is not.
Remediation
Update to version 2.7.23, or a newer patched version
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. None of that substitutes for the fix: Five Star Restaurant Reservations 2.7.23 closes this, and updating the plugin is the step that ends it.
