Technical details

The vulnerability is a SQL injection flaw in the applyMysqlOrPostgresVariables function where user-supplied URL filter values are used unsafely as JavaScript replacement strings in SQL queries. For MySQL and MariaDB, the attacker can additionally exploit unescaped backslash handling in quoted contexts to break out of SQL strings.
