At a glance
CVE-2026-15275 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP Multi Store Locator Pro WordPress plugin, affecting versions <= 4.5.1. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 4.5.2; sites on affected versions should update now. Disclosed September 2026, reported by Rafie Muhammad.
Vulnerability Overview
The WP Multi Store Locator Pro plugin for WordPress is vulnerable to generic SQL Injection via the 'store_locatore_search_radius' parameter in all versions up to, and including, 4.5.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection occurs in a numeric, unquoted SQL context, meaning WordPress's wp_magic_quotes() addslashes-based protection cannot neutralize the payload, and the AJAX handler is registered on wp_ajax_nopriv_make_search_request with no nonce or capability check, making it fully accessible without authentication.
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. A successful exploit has high impact on confidentiality.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
WP Multi Store Locator Pro <= 4.5.1 carries this weakness at store_locatore_search_radius, and reaching it takes no account at all. 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 WP Multi Store Locator Pro the fix is 4.5.2: builds <= 4.5.1 are affected, anything from 4.5.2 onward is not.
Remediation
Update to version 4.5.2, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Multi Store Locator Pro 4.5.2 closes this, and updating the plugin is the step that ends it.
