The Contact Form Email WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and escaping via the name parameter found in the ~/trunk/cp-admin-int-list.inc.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 1.3.24. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.
Stored XSS exists in the Appointment Booking Calendar plugin before 1.3.35 for WordPress. In the cpabc_appointments.php file, the Calendar Name input could allow attackers to inject arbitrary JavaScript or HTML.
The Appointment Booking Calendar plugin before 1.3.35 for WordPress allows user input (in fields such as Description or Name) in any booking form to be any formula, which then could be exported via the Bookings list tab in /wp-admin/admin.php?page=cpabc_appointments.php. The attacker could achieve remote code execution via CSV injection.
The Calculated Fields Form plugin through 1.0.353 for WordPress suffers from multiple Stored XSS vulnerabilities present in the input forms. These can be exploited by an authenticated user.
