Vulnerability Overview

The Qubely plugin for WordPress is vulnerable to unauthorized arbitrary e-mail sending in versions up to, and including, 1.8.5. This is due to insufficient validation on the presence of a contact form block and validation on the email fields in the qubely_send_form_data() function called via an AJAX action. This makes it possible for unauthenticated attackers to send emails with arbitrary content to arbitrary addresses.

Technical Analysis

REMEDIATION: Update to version 1.8.6, or a newer patched version --- IDENTIFIER: CWE-863 (Incorrect Authorization) The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
