AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-12416 and CVE-2026-12417, which involve unauthenticated password reset vulnerabilities in WordPress plugins 'SignUp & SignIn' and 'Invoice Generator'. The exploit leverages weak validation of the 'reset_activation_code' parameter to reset passwords for arbitrary user IDs, including administrators.

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.
