Authenticated database disclosure via unescaped sort expression
Published Jul 27, 2026 · Updated Jul 27, 2026
SQL injection in customer search in Alex Tselegidis EasyAppointments 1.5.1 and earlier allows remote authenticated users to read database data. Customers_model::search passes the order_by request value to CodeIgniter Query Builder, whose identifier protection leaves parenthesized expressions unescaped and executable as SQL. An administrator, provider, or secretary account reaches the endpoint; file access requires MySQL FILE privilege, while shell writing also requires stacked queries that default CI3/PDO disables.
