Advisory
Source description from Wordfence Intelligence, credited to nthng.
VikAppointments Service Booking Calendar wordpress plugin is vulnerable to unauthenticated SQL injection due to one of the parameters that controls how the public reviews list is sorted is taken from the incoming request and used to build a database query without proper validation or sanitization. Because this value is placed directly into the query, an attacker who is not logged in can inject arbitrary SQL through a normal booking page and read data from the site's database — including sensitive information such as WordPress user credentials. No authentication or special privileges are required
