Source record

Technical description

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.
