CVE-2025-12842 Medium · 5.3 CWE-20 Nov 19, 2025

Booking Plugin for WordPress Appointments – Time Slot <= 1.4.7 - Unauthenticated Arbitrary Email Sending

The Booking Plugin for WordPress Appointments – Time Slot plugin for WordPress is vulnerable to unauthorized email sending in versions up to, and including, 1.4.7 due to missing validation on the tslot_appt_email AJAX action. This makes it possible for unauthenticated attackers to send appointment notification emails to arbitrary recipients with attacker-controlled text content in certain email fields, potentially enabling the site to be abused for phishing campaigns or spam distribution.
