 "title": "Simply Schedule Appointments <= 1.6.12.35 - Unauthenticated Stored Cross-Site Scripting via Debug Log",
 "description": "The Simply Schedule Appointments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the debug log in versions 1.6.11.9 up to, and including, 1.6.12.35, due to values submitted when an appointment is changed being written to the log, and the log viewer printing the log without output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the debug log.",
