At a glance

CVE-2026-120043 is a high-severity Improper Neutralization of Special Elements used in an SQL Command vulnerability in the Affiliate Program Suite WordPress plugin, affecting versions <= 1.2.14. 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 1.2.15; sites on affected versions should update now. Disclosed November 2026, reported by Kuba.

Vulnerability Overview

The Affiliate Program Suite — SliceWP Affiliates plugin for WordPress is vulnerable to generic SQL Injection via the 'email' parameter in all versions up to, and including, 1.2.14 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 is reachable without any account because the vulnerable code path is triggered via the user_register hook fired on every successful WooCommerce My Account registration, which requires only a guest-obtainable nonce.

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

Affiliate Program Suite <= 1.2.14 carries this weakness at email, 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 Affiliate Program Suite the fix is 1.2.15: builds <= 1.2.14 are affected, anything from 1.2.15 onward is not.

Remediation

Update to version 1.2.15, 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: Affiliate Program Suite 1.2.15 closes this, and updating the plugin is the step that ends it.
