At a glance

CVE-2026-92554 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the ShopLentor WordPress plugin, affecting versions <= 3.5.1. 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 3.5.2; sites on affected versions should update now. Disclosed September 2026, reported by Kuba.

Vulnerability Overview

The ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via Query-String Parameter Name in all versions up to, and including, 3.5.1 due to insufficient input sanitization and output escaping. 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. The vulnerability is triggered via the WL: Product Horizontal Filter widget, which reflects attacker-supplied query-string parameter names from the current URL into option element value attributes without escaping, allowing payload breakout from the value="..." attribute context.

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 ShopLentor <= 3.5.1 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 ShopLentor the fix is 3.5.2: builds <= 3.5.1 are affected, anything from 3.5.2 onward is not.

Remediation

Update to version 3.5.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to ShopLentor: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ShopLentor 3.5.2 closes this, and updating the plugin is the step that ends it.
