CVE-2026-6235 (GCVE-0-2026-6235)

Title
Sendmachine for WordPress <= 1.0.20 - Unauthenticated SMTP Hijack to Privilege Escalation via manage_admin_requests
Summary
The Sendmachine for WordPress plugin for WordPress is vulnerable to authorization bypass via the 'manage_admin_requests' function in all versions up to, and including, 1.0.20. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the plugin's SMTP configuration, which can be leveraged to intercept all outbound emails from the site (including password reset emails).
