CVE-2023-36510 is a medium-severity Missing Authorization vulnerability in the ReDi Restaurant Reservation WordPress plugin, affecting versions <= 23.0211. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 23.0212; sites on affected versions should update now. Disclosed June 2023, reported by Abdi Pranata.

Vulnerability Overview

The ReDi Restaurant Reservation plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on the redi_restaurant_ajax() function in versions up to, and including, 23.0211. This makes it possible for unauthenticated attackers to modify the plugin's settings

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

ReDi Restaurant Reservation <= 23.0211 carries this weakness at redi_restaurant_ajax(), 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. For ReDi Restaurant Reservation the fix is 23.0212: builds <= 23.0211 are affected, anything from 23.0212 onward is not.

Remediation

Update to version 23.0212, 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: ReDi Restaurant Reservation 23.0212 closes this, and updating the plugin is the step that ends it.
