Disclosed September 2021, reported by Shivam Rai.

Vulnerability Overview

The Restaurant Menu by MotoPress WordPress plugin before 2.4.2 does not properly sanitize or escape inputs when creating new menu items, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

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

Reaching this weakness in Restaurant Menu and Food Ordering < 2.4.2 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 Restaurant Menu and Food Ordering the fix is 2.4.2: builds < 2.4.2 are affected, anything from 2.4.2 onward is not.

Remediation

Update to version 2.4.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Restaurant Menu and Food Ordering: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Restaurant Menu and Food Ordering 2.4.2 closes this, and updating the plugin is the step that ends it.
