Code Injection in Customer Support Ticket System & Helpdesk (WordPress plugin) (CVE-2026-15011)
Summary
Code injection in Customer Support Ticket System & Helpdesk (WordPress plugin) (CVE-2026-15011). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
The Customer Support Ticket System & Helpdesk plugin for WordPress is vulnerable to Code Injection via the 'path' parameter in all versions up to, and including, 6.0.5 due to the use of dynamic function invocation on an attacker-controlled value with insufficient validation. This makes it possible for unauthenticated attackers to invoke arbitrary parameterless PHP functions, which can be used to disrupt site functionality or expose sensitive information. The required nonce is publicly emitted via wp_localize_script whenever the plugin's [emd_form] shortcode is rendered on any public-facing page, making the endpoint reachable by unauthenticated visitors without any prior authentication or privilege.
