Description
Froxlor before 2.3.14 contains an insecure direct object reference vulnerability in the email template editor (admin_templates.php) because the mail body is fetched by mailbodyid without an adminid ownership check. Authenticated reseller admins can pair their own subjectid with sequential foreign mailbodyid values in edit requests to read other admins' email templates, including the full administrator's.
