At a glance
CVE-2023-36506 is a medium-severity Missing Authorization vulnerability in the YITH WooCommerce Waitlist WordPress plugin, affecting versions <= 2.6.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.6.1; sites on affected versions should update now. Disclosed August 2023, reported by thiennv.
Vulnerability Overview
The YITH WooCommerce Waiting List plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.6.0. This is due to missing or incorrect nonce validation on the 'save_mail_status' function. This makes it possible for unauthenticated attackers to enable or disable email notifications via a forged request granted they can trick a site administrator 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-862: Missing Authorization
YITH WooCommerce Waitlist <= 2.6.0 carries this weakness at save_mail_status, 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 YITH WooCommerce Waitlist the fix is 2.6.1: builds <= 2.6.0 are affected, anything from 2.6.1 onward is not.
Remediation
Update to version 2.6.1, 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: YITH WooCommerce Waitlist 2.6.1 closes this, and updating the plugin is the step that ends it.
