Detailsinfo

A vulnerability was found in LevelFourStorefront Shopping Cart & Ecommerce Store Plugin up to 5.9.2. It has been classified as problematic. Affected is the function ec_ajax_save_page_options. The manipulation of the argument product_order with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Shopping Cart & eCommerce Store plugin for WordPress is vulnerable to generic SQL Injection via the 'product_order' parameter in all versions up to, and including, 5.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: the payload is written to the ec_pageoption table via the ec_ajax_save_page_options handler — which applies no sanitization to raw $_POST values — and is later retrieved with stripslashes() (bypassing WordPress magic-quotes protection) before being concatenated directly into SQL on every store page render.

The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-17589 since 07/27/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation needs additional levels of successful authentication. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 09/01/2026). The MITRE ATT&CK project declares the attack technique as T1505.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
