At a glance
CVE-2026-15351 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WC Vendors WordPress plugin, affecting versions <= 2.7.0. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Shop Manager level or above. The issue is fixed in version 2.7.1; sites on affected versions should update now. Disclosed August 2026, reported by Wordfence PRISM.
Vulnerability Overview
The WC Vendors – WooCommerce Multivendor, WooCommerce Marketplace, Product Vendors plugin for WordPress is vulnerable to generic SQL Injection via the 'status' parameter in all versions up to, and including, 2.7.0 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 shop manager-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The sanitize_text_field callback strips HTML but leaves SQL metacharacters intact, and wp_magic_quotes slash protection does not apply because WP_REST_Server::serve_request() calls wp_unslash() on GET parameters before the sanitize callback executes.
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. A successful exploit has high impact on confidentiality.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
WC Vendors <= 2.7.0 carries this weakness at status, and reaching it takes an account at Shop Manager level or above. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For WC Vendors the fix is 2.7.1: builds <= 2.7.0 are affected, anything from 2.7.1 onward is not.
Remediation
Update to version 2.7.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Shop Manager access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WC Vendors 2.7.1 closes this, and updating the plugin is the step that ends it.
