It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 24.1015; sites on affected versions should update now. Disclosed October 2024, reported by vgo0.

Vulnerability Overview

The ReDi Restaurant Reservation plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 24.0902. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in ReDi Restaurant Reservation <= 24.0902 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For ReDi Restaurant Reservation the fix is 24.1015: builds <= 24.0902 are affected, anything from 24.1015 onward is not.

Remediation

Update to version 24.1015, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to ReDi Restaurant Reservation: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ReDi Restaurant Reservation 24.1015 closes this, and updating the plugin is the step that ends it.
