Vulnerability in Invoice Generator (WordPress plugin) (CVE-2026-12416)
Summary
Vulnerability in Invoice Generator (WordPress plugin) (CVE-2026-12416). Successful exploitation can lead to full system takeover. Exploitable via reset_activation_code.
Original description
The description as published by the source.
The Invoice Generator plugin for WordPress is vulnerable to Account Takeover via Password Reset in all versions up to, and including, 1.0.0. This is due to the pravel_invoice_change_password() function being registered as a nopriv AJAX handler with no nonce verification and no authorization check, and performing a loose equality comparison between the supplied reset_activation_code POST parameter and the target user's stored forgot_email user meta — a check that trivially evaluates to true ('' == '') for any user who has never initiated a forgot-password request, which applies to administrators under normal conditions. This makes it possible for unauthenticated attackers to supply an arbitrary user ID via the reset_user_id POST parameter, bypass the activation code check entirely by omitting reset_activation_code, and set the target account's password to an attacker-chosen value, enabling full takeover of any account on the site, including administrator accounts.
