ELEX HelpDesk plugin allows anyone to delete files

CVE-2026-114630 · published 3 days ago
Summary

The ELEX HelpDesk & Customer Ticketing System plugin for WordPress can be tricked into deleting any file on the web server, even without logging in. An attacker can place a malicious file path when submitting a ticket and then trigger a reset routine that removes that file, potentially damaging the site or allowing further attacks. Update the plugin beyond version 3.3.8 or remove it until a safe version is available.

Original advisory text
ELEX WordPress HelpDesk & Customer Ticketing System <= 3.3.8 - Unauthenticated Arbitrary File Deletion via 'ticket_attachment_path' Parameter
The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the factory_reset function in all versions up to, and including, 3.3.8 This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This vulnerability is exploitable via a two-step chain: an unauthenticated attacker first stores an arbitrary ticket_attachment_path value by submitting a ticket through the nopriv eh_crm_new_ticket_post AJAX endpoint (whose nonce is publicly exposed via the [wsdesk_support] shortcode), then triggers the factory_reset routine via a GET request to wp-admin/admin.php?page=wsdesk_factory_reset, which is guarded only by is_admin() — a request-type check — rather than a capability check, causing unlink() to be called on the attacker-supplied path.
