What the vulnerability does
The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the 'eh_crm_agent_add_user' AJAX action in all versions up to, and including, 3.2.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create new administrative user accounts.
Explanation of Vulnerability in Simple Terms
The ELEX WordPress HelpDesk & Customer Ticketing System plugin through version 3.2.6 fails to properly check user permissions before allowing access to sensitive functions. A logged-in user with low privileges can perform actions they should not be authorized to do, including reading, modifying, or deleting data. This affects confidentiality, integrity, and availability of the ticketing system.
What an attacker can do
A low-privilege user can read, modify, or delete tickets and data they should not have access to.
Potential impact on your site
Ticket data, customer information, and support workflows can be compromised by any logged-in user, even those without admin or support staff roles.
Conditions required to exploit
Attacker must have a valid WordPress user account with low privileges (e.g., subscriber or contributor role).
