CVE-2026-115820: SQL Injection (CVSS 6.5)

Description

The Majestic Support – The Leading-Edge Help Desk & Customer Support Plugin plugin for WordPress is vulnerable to generic SQL Injection via the 'columns (array keys)' parameter in all versions up to, and including, 1.2.2 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 subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Any authenticated WordPress user with Subscriber-level access can exploit this because the 'saveusereraserequest' task is whitelisted for front-end customer use, the plugin auto-provisions a help-desk record for every WordPress account, and the only guard is a nonce the attacker legitimately obtains from their own 'Add erase request' page.
