A significant security flaw has been identified in the ELEX WordPress HelpDesk & Customer Ticketing System plugin, affecting many WordPress users. This vulnerability, known as an Insecure Direct Object Reference (IDOR), could allow unauthorized access to sensitive customer support ticket information.
In simple terms, an IDOR vulnerability occurs when an application uses an ID to directly access an object (like a support ticket) without properly checking if the user making the request is authorized to view that specific object. Think of it like being able to change a number in a web address to view someone else’s private document, even if you don’t have explicit permission.
For the ELEX WordPress HelpDesk plugin, this means that an attacker with even a low-level authenticated account, such as a Subscriber, could potentially read the content of all support tickets. This is possible because the plugin lacks crucial validation checks when a user attempts to view a ticket through the ‘eh_crm_ticket_single_view_client’ function.
CVE Details
- Product: ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress
- Published Date: November 21, 2025

- Status: Analyzed
Affected Products
The vulnerability impacts all versions of the ELEX WordPress HelpDesk & Customer Ticketing System plugin up to, and including, version 3.2.9.

Severity Level
Rated as Medium severity with a CVSS score of 4.3, this vulnerability should not be overlooked. Although it requires an authenticated user (meaning a hacker needs to have some form of user account on your WordPress site), the potential impact is the unauthorized disclosure of private customer support interactions.
