At a glance

CVE-2025-11518 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the WPC Smart Wishlist for WooCommerce WordPress plugin, affecting versions <= 5.0.3. 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 5.0.4; sites on affected versions should update now. Disclosed October 2025, reported by Athiwat Tiprasaharn (Jitlada).

Vulnerability Overview

The WPC Smart Wishlist for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.0.3 via several wishlist AJAX functions due to missing validation on a user controlled key that is exposed when wishlists are shared. This makes it possible for unauthenticated attackers to empty and add to other user's wishlists, if they have access to the key.

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-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in WPC Smart Wishlist for WooCommerce <= 5.0.3 takes no account at all. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For WPC Smart Wishlist for WooCommerce the fix is 5.0.4: builds <= 5.0.3 are affected, anything from 5.0.4 onward is not.

Remediation

Update to version 5.0.4, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: WPC Smart Wishlist for WooCommerce 5.0.4 closes this, and updating the plugin is the step that ends it.
