AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-13262, an authenticated SQL injection vulnerability in Majestic Support WordPress plugin (<=1.1.9). The exploit demonstrates how a Subscriber-level user can extract password hashes via a UNION-based SQLi in the `get-smart-reply` AJAX action due to improper use of `esc_sql()` in an unquoted numeric context.

Description

The Majestic Support – The Leading-Edge Help Desk & Customer Support Plugin plugin for WordPress is vulnerable to generic SQL Injection via the 'val' parameter in all versions up to, and including, 1.1.9 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. Exploitation requires a valid 'get-smart-reply' nonce, which any Subscriber-level user can obtain by creating a ticket via the public frontend and visiting the resulting ticket detail page, making this effectively exploitable by any authenticated user.
