InfusedWoo Pro <= 5.1.18 - Authenticated (Subscriber+) Privilege Escalation via Password Reset Link Disclosure

The InfusedWoo Pro plugin for WordPress is vulnerable to Privilege Escalation via Account Takeover in all versions up to, and including, 5.1.17. This is due to a missing capability check in the `ajax_iwar_preview_email()` function, which uses `is_admin()` as its only authorization check and allows low-privilege users to render email preview merge fields for an arbitrary email address. This makes it possible for authenticated attackers, with subscriber-level access and above, to generate and retrieve a valid password reset link for any WordPress user, including administrators, enabling account takeover.
